Patrick Walton ee6c7e0797 Explicitly cast `aTessCoord` to `vec2` for WebGL compatibility 2020-02-28 12:49:21 -08:00
Patrick Walton 5421525eaa Implement the HSL filters (called "non-separable blend modes" in the spec). 
These cannot be implemented with the standard OpenGL blending functions, so we
have to do them manually in a shader, which requires a good deal of machinery
to create intermediate framebuffers and so forth.
