We were lacking support for default textures (i.e. calling `glBindTexture` with a `texture` argument of `0`) which caused our Quake2 port to render red screens whenever a video was playing. Every texture unit is now initialized with a default 2D texture. Additionally, we had this concept of a "currently bound target" on our texture units which is not how OpenGL wants us to handle targets. Calling `glBindTexture` should set the texture for the provided target only, making it sort of an alias for future operations on the same target. Finally, `glDeleteTextures` should not remove the bound texture from the target in the texture unit, but it should reset it to the default texture. |
