alternative from mk/jpeg.buildlink3.mk
This allows selection of an alternative jpeg library (namely the x86 MMX,
SSE, SSE2 accelerated libjpeg-turbo) via JPEG_DEFAULT=libjpeg-turbo, and
follows the current standard model for alternatives (fam, motif, fuse etc).
The mechanical edits were applied via the following script:

4. Version 7.5 Release Notes:
---------------------------------
Version 7.5 is the development branch. Version 7.5.0 is the same as
7.4.2, which is essentially the same as 7.3.123, plus some
documentation updates. Intended development is as follows:
1) Use a finely spaced grid for the database, but keep the concept
of "lambda" for layout. Keep backwards compatibility, and resolve
issues with layout that does not work well on the lambda grid.
Item #1 implemented in 7.5.1 by allowing a DRC "scalefactor" line,
which declares that all DRC rules are in units of (lambda /
scalefactor). Rules "in use" are scaled to lambda and rounded to
the nearest integer. The original value is retained, however, so
that any call to "scalegrid" will recompute the DRC distances based
on the current internal grid. Thus, we can define DRC rules in
fractional lambda and therefore match vendor DRC rule distances
while still maintaining magic's concept of "lambda". This means
that users working entirely within magic have scalable CMOS rules,
but if a "vendor cell" (3rd party GDS or CIF) is loaded, the DRC
rules will be correct with respect to it.
2) Create tile-based DRC functions that work like cifoutput: perform
tile operations, for which the resulting plane, instead of being
output as a file like CIF or GDS, simply becomes an error result
plane. This will become an extra built-in plane. Try to keep the
plane numbers down by removing the built-in routing planes when they
are not used.
Basically, this means that the top of the DRC section defines a set
of "templayer" blocks just like "cifinput" and "cifoutput" (but at the
same scaling as the layout (thus the main reason for item #1 above)),
where the templayer types can be used in the DRC section.
3) Add "cifoutput" operators as needed to form a complete DRC. Add DRC
rule types as needed to form a complete DRC (for example, it needs a
"copy" function that declares that the templayer itself represents the
error condition).
4. Version 7.4 Release Notes:
---------------------------------
Version 7.4 is the new stable distribution version of magic.
Apart from changes to the release notes, it is identical to
the last revision (123) of development version 7.3. Revisions
of 7.4 will be made as necessary to fix bugs in the code. All
new additions and major changes will be done to the new
development distribution, version 7.5. Therefore there will
not be a "What's new in 7.4" section, as there is not supposed
to be anything new in version 7.4.
5. Version 7.3 Release Notes:
---------------------------------
Magic release 7.3 incorporates a stacked contact model which is,
for the most part, backwardly compatible with Magic releases
7.2 and earlier. Information about this developmental release
can be found at:
http://opencircuitdesign.com/magic/magic7_3.html
What's new in 7.3:
------------------
Provided by Tim Edwards (MultiGiG, Inc.):
1) Stacked contact model allowing arbitrary stacking of
contact types.
2) A separate "undo/redo" method for network selection, to
remove the memory overhead associated with selecting and
unselecting large networks. Also removes some time overhead
as well, especially when unselecting networks.
3) Much improved "plot pnm" function.
4) Improved transistor and resistor extraction.
5) LEF format reader; improved LEF/DEF input/output handling
6) New style and colormap file formats
7) Vendor GDS read/write capability
8) "wire segment" drawing function
9) Handling of path records in CIF and GDS input
10) Handling of cell scaling in GDS input
11) Pi-network device extraction for resistors
12) Option to write contacts as cell arrays in GDS output
13) New "widespacing" and "maxwidth" DRC algorithms.
14) "polygon" command
15) New cifoutput operator "bloat-all"
16) Backing-store for 24-bit and OpenGL graphics
17) New "pick" tool for interactive selection move and copy
18) New interactive "wire" tool
19) Crosshair
20) New cifoutput operator "slots"
21) New fcntl-based file locking mechanism
22) "angstroms" units supported in cifinput/cifoutput
23) Non-Manhattan device extraction support
24) New "feedback" mechanism
25) Proper support for > 32 planes (up to 64)
26) Fixed array interaction CIF/GDS generation
27) Added executable "magicdnull" for streamlined batch-mode use
28) New method for crash backups, including restore with "magic -r"
29) A number of other technology file additions and enhancements
6. Version 7.2 Release Notes:
---------------------------------
Magic release 7.2 incorporates the capability to run magic from the Tcl
interpreter with graphics handled by Tk. Instructions for compiling
and installing this version are in README.Tcl. Information about
this release can be found at:
http://opencircuitdesign.com/magic/magic7_2.html
What's new in 7.2:
------------------
Provided by Tim Edwards (MultiGiG, Inc., and JHU Applied Physics Lab):
1) Tcl interpreter extension option
2) Cygwin compile option
3) Memory resources cleaned up
4) GUI interface to Tcl version of Magic
5) Readline update to version 4.3

9) Inductance extraction
10) CIF and GDS input/output support for deep submicron technologies
11) Different internal and lambda grids, including automatic or
induced ("scalegrid" command) grid subdivision and expansion.
"snap" and "grid" functions and extensions aid layout when
lambda and internal units differ.
12) Removed commands "list", "listall", "parent", and "child",
replacing them with the more general-purpose "cellname"
and "instance" commands.
13) Added command "tech", and re-loadable technologies.
14) Revamped the "dstyle" files and updated the dstyle version
15) Added "element" types for layout annotation.

keyword and devices "mosfet", "bjt", "capacitor", and "resistor".
New model resistor and mosfet use width/length instead of area/
perimeter.
17) Added 3D rendering window invoked by command "specialopen wind3d",
for the Tcl version compiled with OpenGL graphics.
18) Added "height" keyword to tech file for height/thickness values
19) Added "windowname" command for managing multiple wrapper windows
under Tcl.
20) Added extraction extension for annular (ring) MOSFETs.
21) Added "widespacing" DRC rule.
22) Added GNU autoconf compile

(such as LEF/DEF).
24) General-purpose subcircuit method using the "port" command to
declare a cell to be a subcircuit and to mark the position and
orientation of connections into the subcell. This replaces a
method previously built into version 7.2 using a "subcircuit"
layer; that method is now considered obsolete.
25) LEF and DEF format readers, LEF format writer.
26) Improved techfile format with asterisk-notation and DRC
"surround", "overhang", and "rect_only" statements.

changes:
SimPy 2.0.1 is a bug-fix release of SimPy 2.0. It
repairs bugs and imperfections in libraries, documentation
and models.
SimPy 2.0 has been a major release of the SimPy simulation
package. It runs on all platforms supporting Python (MS Windows,Linux, Mac).
The major new features of that release are
* an Object Oriented API (in addition to the existing API),
* integration of all documentation into one browsable
and searchable HTML document.
SimPy 2.0 is fully backwards compatible with previous
SimPy versions.
Besides the changes noted below, a major change in 1.6.0 is that the gEDA/gaf suite
is istributed as a single tarball and uses a single build system as opposed to individual
tarballs and builds. In addition to greatly speeding up the build, it is much easier
to maintain. Additionally, it rarely made sense to only install some of the components.
Notable changes in gEDA/gaf 1.6.0
=================================
* Fixed the GtkItemEntry code inside of gattrib code so that it builds
using gtk+ > 2.16.x.
* In gschem, rubberband pin to pin connections by adding nets.
* Cleanup of the slot handling code in libgeda.
* Fixes/updates to the MinGW port.
* Updated the shipped documentation from the online wiki.
Notable changes in gEDA/gaf 1.5.3/1.5.4
=======================================
* NOTE: gEDA/gaf 1.5.3 was released with some critical bugs, so
it was withdrawn before it was widely distributed.
* Text rendering using native system fonts:
- The various programs in gEDA/gaf no longer uses its own built-in
line font.
- Native system fonts are used for rendering, giving support for a
wider range of symbols, and better looking schematics.
* Always use PostScript fonts in gschem's PostScript output. The
"output-text", "text-output" and "output-vector-threshold" config
functions have been removed.
* Image rendering in 'gschem' uses cairo instead of GDK.
* Numerous build system changes:
- gEDA/gaf is now distributed as a single source archive, called
gEDA-<version>.tar.gz.
- GTK+ 2.10 or newer and Guile 1.8 or newer are now required.
- `intltool' is no longer required.
- Documentation is now installed to ${docdir} (usually
${prefix}/share/doc/gEDA).
* The attribute edit dialog in `gschem' now has completion of most
common attribute names.
* The multi-attribute edit dialog in `gschem' now shows unpromoted
symbol attributes.
* Menu items in `gschem' now have icons and properly aligned key
bindings. They also support accelerator keys.
* The `gschem2pcb' and `PCBboard' netlist backends have been removed.
It is recommended to use `gsch2pcb' instead.
* Check for and reject non-footprint PCB files in 'gsch2pcb'.
* Removed unimplemented "File->Open" feature in 'gattrib'.
* Added --disable-gattrib command line flag to ./configure to disable the
building of 'gattrib'. This is useful if you are building against
gtk+ 2.17.x which breaks 'gattrib'.
* 'gnetlist' does not recommend drc2 every time it runs. The drc2
backend is only useful in certain circumstances.
* Assign shortcuts "vd" and "vl" for changing between color schemes
in 'gschem'.
* Fix problem with attached net attribute not being honored in 'gnetlist'.
* Focus the "save" button in the close confirmation dialog in 'gattrib' and
'gschem'.
* Accept empty attributes in the src file in 'tragesym'.
* Cleaned up the slot dialog box in 'gschem'.
* Changed the grip size rendering in 'gschem' to be reasonably sized when
zoomed in a lot.
* Introduction of a new attribute searching API in 'libgeda' and 'gschem'.
* Improvements and cleanup to the 'gnetlist' and 'gsymcheck' test suites.
* Fixed the following bugs:
- 1758673: Combine source tarballs
- 2058707: gschem, gattrib: Dangerous button focus in "Save changes"
dialog at quit
- 2430369: gschem: Deselect invisible attribs with their parent object.
- 2449060: Graphic state left inconsistent cancelling from net mode
- 2460301: libgeda: Make o_complex_promote_attribs() respect keep_invisible
and libgeda: Make o_complex_copy() actually copy.
- 2455061: Gnetlist output changed, and tests fail with recent GLib
- 2655088: autogen.sh: Make sure to exit if autopoint fails.
- 2823703: gnet-pcbpins.scm: Quote pins names if they contain comma
or close parenthesis.
- 2823755: gnetlist: Fix DEBUG builds.
- 2836109: build-sys: Add check for groff html driver.
* Spanish translation were updated.
* Lots of code, infrastructure, and doxygen documentation cleanup and
refactoring.
Notable changes in gEDA/gaf 1.5.2
=================================
* `gschem' now uses Cairo for all rendering. This allows for
everything to be rendered anti-aliased.
* `gschem' now uses a mesh grid instead of dots by default.
* Net junction cues in `gschem' are drawn smaller now.
* Copy and paste now works between different `gschem' instances (using
the X selection).
* Recent files are no longer opened in a new `gschem' window.
* Major, *backwards-incompatible* changes to color handling in
`libgeda' and `gschem'.
- All colors are specified using hexadecimal `#RRGGBB' or
`#RRGGBBAA' syntax.
- The print and display color maps are now separate.
- A new Scheme syntax is used to inspect and modify color maps.
- If you wish to use a light background in `gschem', add the line:
(load (build-path geda-rc-path "gschem-colormap-lightbg"))
to your personal or project gschemrc file.
* Attributes of embedded objects are now shown in the right color.
* Bus pins are now supported by `gschem' and `libgeda', but are *not*
properly supported by the netlister. The pin type can be modified
by selecting a pin, then right-clicking it and selecting `Edit pin
type...'.
* All of the symbols were modified to use overbar markup tags ("like
\_this\_") instead of separate lines.
* Log files are now saved to $HOME/.gEDA/logs rather than being
dropped in the current directory.
Notable changes in gEDA/gaf 1.5.1
=================================
* GTK+ version 2.8.x or later is now required.
* The selection behaviour in `gschem' was changed.
- Lines, unfilled boxes, unfilled circles, arcs, pins, nets, and
buses must be selected by clicking on the drawn path itself.
- Filled boxes, circles, text, and components, may be selected by
clicking anywhere in the bounding box.
- The default mouse click distance required to select an element was
increased to 10 pixels.
- Double-clicking on a net segment selects all connected net
segments.
* The percentage step in or out while zooming the display in `gschem'
is now configurable with the `zoom-gain' gschemrc parameter. The
default value is 20%.
* The size of steps when panning with the mouse wheel or with a
trackpad in `gschem' is now adjustable with the `scrollpan-steps'
gschemrc parameter. The default setting scrolls in steps of 1/8 of
a screen.
* A number of improvements were made to the `gschem' component
selection dialog.
- The dialog now shows a table of top-level attributes in the
selected symbol.
- It is now possible to expand/collapse a library by clicking
anywhere on its row.
* Changes to fill- and line-styles in `gschem' can now be undone.
* Arcs can now be adjusted in `gschem' using an arc angle dialog. It
can be accessed by selecting an arc and selecting Edit->Edit.
* It is now possible to rotate objects while placing them in `gschem'.
* Support for arbitrary filled and unfilled paths, using a subset of
the SVG path syntax. For more information, please see the file
format specification.
<http://geda.seul.org/wiki/geda:file_format_spec>
- `gschem' does not yet provide a GUI for creating or editing path
elements. However, it does support rendering them. They can also
be printed.
- Some of the symbols in the component library were updated to use
paths.
* A Scheme evaluation prompt was added to `gschem'. It can be
accessed by typing `:'.
* Improved algorithm for drawing hatched fills both on screen and in
PostScript output.
* Color selection dialogs and menus in `gschem' now show the actual
color as well as the description. Color names are now translatable.
* `gattrib' now prompts to save changes.
* All of the unimplemented menu items and pages in `gattrib' were
removed.
* The `always-promote-attributes' gafrc parameter now takes a list of
strings as an argument. The space-delimited string syntax is
deprecated.
* Some optimisations were made to the `gnetlist' connection traversal
algorithm to speed up netlisting large designs.
* A new netlist backend was added to support Liquid PCB.
<http://www.liquidpcb.org/>
* The `bom2' netlist backend now generates a `qty' column.
* Several improvements and fixes were made to the `systemc' backend.
* The `--gnetlist-arg' option to gsch2pcb can now be used to pass
extra `gnetlist' arguments.
* `gsch2pcb' now emits files with the latest `pcb' file format.
* The `gxyrs' pick-and-place tool was added.
Notable changes in gEDA/gaf 1.5.0
=================================
* Magnetic net mode in `gschem'. Magnetic mode lets you draw nets and
automatically connect to valid end points (such as pins and other
nets). The `magnetic-net-mode' gschemrc parameter can be used to
enable/disable this feature.
* Rotating a component while moving it in `gschem' now rotates around
the current mouse location.
* The `verilog' and `vhdl' backends now work again.
* Embedded components can now be mirrored.
* The `pads' netlist backend now uses CRLF line endings.
