Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.
to address issues with NetBSD-6(and earlier)'s fontconfig not being
new enough for pango.
While doing that, also bump freetype2 dependency to current pkgsrc
version.

libgambatte:
- Fix HqXx filter pitch.
- Fix mbc2 not getting a rambank.
- Make sure to reset passed pointers when deleted. Fixes potential crash
when loading ROM during OAM busy.
common:
- Substantially improved rate estimation averaging.
- RateEst: Add a convenient way of filtering measures that extend beyond
a buffer time, and are as such probably invalid.
- RateEst: Allow using a custom timestamp in feed().
- RateEst: Keep a queue of the last ~100 msec worth of samples and
duration, and filter out collective samples that give a pre-estimate
that seems way off.
- Replace "Game Boy / Game Boy Color emulator" with "Game Boy Color
emulator" for now to avoid misleading anyone on the current status.
gambatte_qt:
- Disable BlitterWidget updates (paintEvents) while not paused.
- QGLBlitter: Do a cheap front blit rather than a vsynced flip if audio
buffers are low.
- Allow BlitterWidgets to opt in to get paintEvents while unpaused. Do so
for QGLBlitter since it may need to clear buffers afterwards.
- QGLBlitter: Try to blit right after sync in the case of single buffering.
- Up default audio buffer latency to 100 ms (some common system audio
servers require a lot of buffering to work well).
- Adaptively skip BlitterWidget syncs if audio buffer is low, in a manner
that should minimize wasted skips in sync to vblank situation, and tries
to be non-disturbing. This replaces frame time halving, and blitter
specific rescueing.
- Clear display buffers in DirectDrawBlitter and Direct3DBlitter in
exclusive mode, since blits don't necessarily cover the entire buffers.
- DirectDrawBlitter: Make sure that a minimum amount of time has passed
between calls to WaitForVerticalBlank, since it can return in the same
vblank period twice on a fast system.
- DirectDrawBlitter: Support vsync for refresh rate ~= 2x frame rate.
- DirectDrawBlitter: Refactor somewhat and get rid of a couple minor
potential bugs.
- DirectDrawBlitter: Some tweaks to get updates closer to sync time in
certain situations.
- DirectDrawBlitter: Some tweaks to better support DONOTWAIT.
- DirectDrawBlitter: Make only updating during vblank while page flipping
optional.
- Direct3DBlitter: Some tweaks to get updates closer to sync time in
certain situations.
- Filter out very short frame times in frame time estimation.
- Don't adjust frame time during turbo, but rather skip BlitterWidget
syncs to speed up, which avoids vsync limits without disabling vsync.
- DirectDrawBlitter: Add triple buffering option.
- Direct3DBlitter: Use D3DSWAPEFFECT_DISCARD in non-exclusive mode.
- Direct3DBlitter: Allow triple buffering and vblank-only updates in
non-excusive mode.
- Rename "Page flipping" in Direct3D and DirectDraw blitters to
"Exclusive full screen".
- Pause audio on win32 titlebar clicks/drags to avoid looping audio due to
underruns from blocked timerEvents.
- Use wildcards for platform detection to avoid being unnecessarily
compiler/architecture specific. Fixes bug 2377772.
- Rewrite most of DirectSoundEngine, supporting primary buffer option,
making it more robust, correct and hopefully cleaner. Only use part of
the primary buffer if the desired buffer size is lower than the
primary buffer size.
- Direct3DBlitter and DirectDrawBlitter: Force blocking updates when sync
to vblank is enabled. Some updates only block if there's a prior
unfinished update in progress. This screws up frame time estimation in
turn screwing up vsync. To fix this we do a double update (and extra blit)
if close to a frame time period has passed since the last update when
sync to vblank is enabled. I really should have noticed this earlier as
it pretty much breaks vsync adaption completely.
- Direct3DBlitter: Use the D3DCREATE_FPU_PRESERVE flag when creating
device. Omitting this flag can screw up floating point calculations in
other parts of the code. For instance WASAPI cursor timestamps get
utterly screwed up here.
- Direct3DBlitter: It appears that managed textures are updated before
they are unlocked, which screws up redraws, making things appear choppy
in some situations. Use a default memory texture and a system memory
texture and the UpdateTexure method instead.
- DirectSoundEngine: Make use of the sample period limit feature of
RateEst, rather than duplicating the feature.
- Add polling WASAPI engine with exclusive mode support. Latency and rate
estimation is generally better than DirectSound, and in exclusive mode
there is less blocking as well as exclusive mode being better than
shared mode in the other areas too.
- WasapiEngine: Add device selection.
- WasapiEngine: Add static isUsable() method. Only listed if isUsable().
Default engine if isUsable().
- WasapiEngine: Use default device if there's only one device available,
since we don't show the combobox anyway.
- DirectSoundEngine: Provide the integrated read and status get write
method optimization.
- XvBlitter: Set NosystemBackground attribute rather than OpaquePaintEvent.
Reimplement paintEngine to return NULL as suggested by Qt docs.
- X11Blitter: Reimplement paintEngine to return NULL.
- AlsaEngine: Make use of sample period limit feature of RateEst. Don't
increase estimated sample rate on underrun.
- OssEngine: Make use of sample period limit feature of RateEst. Don't
increase estimated sample rate on underrun.
- Esc exits fullscreen on macx.
- Drop OpenAL from default macx binary.
- Add some useful but commented build flags for macx to .pro files.
Gambatte is an accuracy-focused, open-source, cross-platform Game
Boy / Game Boy Color emulator written in C++. It is based on hundreds
of corner case hardware tests, as well as previous documentation
and reverse engineering efforts.
