util/geometry: fix bad assumption in lineseg_closest_factor_impl
cabs2(a - b) may return 0 even if a != b, if the difference is
sufficiently small.

lasers: improve collision; move to lasers/
Moved quantization out of the draw code. The laser is now quantized once
per frame, and the segment data is used for both collisions and
rendering. Player motion is now accounted for as well, preventing
phasing through thin lasers. The overall result is more precise *and*
faster collision detection.

geometry: rework lineseg_circle_intersect; add a few useful functions
Fixed a false negative in lineseg_circle_intersect that could occur when
the closest point lies outside the line segment, yet the segment is
still within the circle's radius. Optimized to avoid square roots. Added
functions for querying the closest point on a line segment without
distance restrictions.

Don't redefine standard complex macro; use a new cmplx typedef
This also introduces `float32`, `float64`, and `real` typedefs to be
used in place of `float` and `double` later. `real` is for game code and
other places where we don't particularly care about the precision and
format of the underlying type, and is currently defined to `double`.
`float32` and `float64` should replace `float` and `double` respectively

fix broken laser collision after merging #151
also add a parameter to rect_rect_intersect{,ion} to specify whether to
register shader corners/vertices as intersections. previously these
would be unconditionally discarded.

Some renderer refactoring (mostly API and GLES preparations) (#144)
* Refacor uniforms API:

    - More complete and consistent
    - Type-safety
    - Usage correctess assertions missing for now, planned

* Redesign texturing API: texunits gone, assign textures to sampler uniforms directly

r_texture_create now allocates memory and returns an opaque Texture
pointer; similar changes to the other renderer APIs will follow.

* Framebuffers: make _create return an opaque pointer, add debug label APIs (unused for now)

* opaque pointers and debug label APIs for vertex arrays and buffers

* fix null renderer

* Refactor glsl preprocessing into an independent module

* Separate shader resource management from renderer backend

This makes it possible to add more shading languages and/or include a
transpiler, which will be useful for the GLES backend.

* refactor r_clear into a stateless API

* add r_texture_clear API; fix gl33_framebuffer_clear

* Replace deprecated glsl_objects with objects in all *.prog files

* fix missing texture_clear implementation in null renderer

* remove some dead code in null renderer

* fix GLES segfault

* GLES 3.0 actually has glVertexAttribDivisor

* Query GL for supported GLSL versions (preparing to add shader transcompilation)

Text rendering rewrite and optimizations; some refactoring (#129)
* wip font rendering stuff; hashtable monstrosity is temporary

* various text rendering fixes/improvements

* HashTables™ 3.0

* Add some comments to aid navigating the hashtable macro maze

* overhaul text rendering API; add default and example shaders

* text: implement text_render for spellcard effect; misc fixes

* README: update dependencies

Bye SDL_ttf, hello freetype2.

* text_draw: fix resolution/scale-dependent bugs

* make text_draw fallback to the current shader, fix hud and stagetext

* repair the bgm loading

* fix spell practice mode

* fix walloftext

forgot one site of text_draw earlier

* fix wrapped text rendering

* fix and simplify the hud text shader

* dynamic glyph cache

* implement font size change on window resize/quality setting change/etc.

* rename text shaders for consistency

* preloads for fonts and text shaders

* make the stagetext shader look somewhat better

* text_render: attempt to normalize height

* small improvement for stagetext
