Hi guys,
Is there any reason we need to update tex combiner state if we are
using shaders?
can we drop update_tex_combine updates to only the case where we don't
have a fragment shader/program unless its from the FF shader?
I don't recall when update_tex_combine happens. Does it happen at
draw-time or state change-time? If it happens at state change-time, the
state will need to get updated when program 0 gets bound. Otherwise
something like the following would break:
glUseProgram(my_prog);
glTexEnvi(GL_TEXTURE_2D, GL_TEXTURE_ENV_MODE,
GL_DECAL);
glUseProgram(0);
glDrawArrays(...);
