* Implement Robin Hood hashing
This replaces the previous separate chaining implementation. This
approach is more memory-efficient, cache-friendly, and puts much less
stress on the memory allocator.
* Replace crc32 with fnva1
Also attempt to make the compiler pre-hash as much stuff as possible at
build time.
* WIP gles2 compat
* More gles2 compat. Playable with ANGLE now, with some rendering bugs.
* fix matrix mult. order in generic laser shader
* gles20: fix indexed rendering
* Update docs about gles20 status
* fix formatting
* 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)
* 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
