Hi, when looking at a regression (piglit ext_transform_feedback-immediate-reuse-uniform-buffer, bug 90081) I realized that behavior wrt non-size-aligned constant buffers doesn't seem to be all that clear cut. In particular I'm wondering if what the test (or rather the state tracker) does is actually ok? Constant buffers were always really considered to have been consisting of vec4 of floats (they are accessed with xyzw semantics after all), hence having a constant buffer with a size not a multiple of 16 bytes seems rather odd. I wonder though if they need to be handled gracefully somehow (of course, in usual GL fashion, nobody has any idea that this spiffy 4-byte transform feedback or whatever different bind point buffer is going to be used as a constant buffer later), or if this is something which should be addressed elsewhere.
