* WIP compressed textures, swizzles, sRGB sampling, ... * refactor texture type info & fix random bugs * fix preprocessing of sRGB textures * handle y-flipped basis textures * glcommon: better WebGL compat for compressed format detection * missed WEBGL_compressed_texture_pvrtc * implement compressed texture xcoding and uploading * Add basis_universal submodule * Reorganize texture loader code Clean up some code Isolate Basis Universal loader into a separate module * Add wrapper script for encoding .basis textures * basisu: honor custom metadata written by the mkbasis.py script * mkbasis.py: add --incredibly-slow and --dry-run * Move pixmap code from util/ to pixmap/ * Add an on-disk transcode cache for basis textures to speed up loads * Compress texture cache with zlib * Use readable format names for basisu cache filenames * basisu: mip bias test code * basisu: small caching cleanup * add TAISEI_BASISU_MIP_BIAS env variable * Improve OpenGL format matching heuristics * Document considerations for compressed format priority * Remove dead code * Enable two forgotten formats, BC3_RGBA and ATC_RGBA Also prefer BC7 over BC1/BC3 * Recognize GL_ANGLE_compressed_texture_etc for ETC2 textures * Default depth buffers to 24-bit; remove ANGLE hack * Fix glcommon_check_extension for GLES2/legacy gl * Add renderer feature bit for texture swizzle masks * glcommon: Fixup internal formats for GLES2 Sized internal formats are not allowed in GLES2 * Fix emscripten compile errors * Update basis_universal * remove more dead code * revert irrelevant stage4 change * shut up UBSan * basisu: shut up some debug spam * Add normalmap sampling helper to util.glslh * basisu: add a gray-alpha mode * mkbasis.py: Abort if image dimansions aren't multiples of 4 * Add basic Basis Universal encoding documentation (WIP) * doc/basisu: Add paragraph about modes; minor tweaks * basisu: workarounds for GL texture size requirements * gles20: fix uncompressed sRGB formats * Partial workaround for missing swizzles in gles2 and webgl * remove invalid assertion * New renderer API to expose glDrawBuffers-like functionality * stagedraw: disable all color outputs for copy_depth pass required for WebGL compatibility * support GL_ANGLE_request_extension * emscripten: include *.basis in gfx package Also fix a potential problem when more than one .pkgdir is used to construct emscripten packages * Don't rely on emscripten runtime to enable webgl extensions
