-/* The hardware only supports immediate constants inside the fragment program,

- *
- * Hence, we need to patch the fragment program itself both to update constants
- * and update linkage.
- *
- * Using a single fragment program would entail unacceptable stalls if the GPU is
- * already rendering with that fragment program.
- * Thus, we instead use a "rotating queue" of buffer objects, each of which is
- * packed with multiple versions of the same program.
- *
- * Whenever we need to patch something, we move to the next program and
- * patch it. If all buffer objects are in use by the GPU, we allocate another one,
- * expanding the queue.
- *
- * As an additional optimization, we record when all the programs have the
- * current input slot configuration, and at that point we stop patching inputs.
- * This happens, for instance, if a given fragment program is always used with
- * the same vertex program (i.e. always with GLSL), or if the layouts match
- * enough (non-GLSL).
- *
- * Note that instead of using multiple programs, we could push commands
- * on the FIFO to patch a single program: it's not fully clear which option is
- * faster, but my guess is that the current way is faster.
- *
- * We also track the previous slot assignments for each version and don't
- * patch if they are the same (this could perhaps be removed).
