Unknown W. Brackets 4731a2918c GPU: Use more typesafe shader IDs. 
Since they really are fairly distinct, let's make sure we can't mix them
accidentally.

// Ideas for speeding things up on mobile OpenGL ES implementations
//
// Use superbuffers! Yes I just invented that name.
//
// The idea is to avoid respecifying the vertex format between every draw call (multiple glVertexAttribPointer ...)
// by combining the contents of multiple draw calls into one buffer, as long as
// they have exactly the same output vertex format. (different input formats is fine! This way
// we can combine the data for multiple draws with different numbers of bones, as we consider numbones < 4 to be = 4)
// into one VBO.
//
// This will likely be a win because I believe that between every change of VBO + glVertexAttribPointer*N, the driver will
// perform a lot of validation, probably at draw call time, while all the validation can be skipped if the only thing
// that changes between two draw calls is simple state or texture or a matrix etc, not anything vertex related.
// Also the driver will have to manage hundreds instead of thousands of VBOs in games like GTA.
//
// * Every 10 frames or something, do the following:
// - Frame 1:
// + Mark all drawn buffers with in-frame sequence numbers (alternatively,
// just log them in an array)
// - Frame 2 (beginning?):
// + Take adjacent buffers that have the same output vertex format, and add them
// to a list of buffers to combine. Create said buffers with appropriate sizes
// and precompute the offsets that the draws should be written into.
// - Frame 2 (end):
// + Actually do the work of combining the buffers. This probably means re-decoding
// the vertices into a new one. Will also have to apply index offsets.
//
// Also need to change the drawing code so that we don't glBindBuffer and respecify glVAP if
// two subsequent drawcalls come from the same superbuffer.
//
// Or we ignore all of this including vertex caching and simply find a way to do highly optimized vertex streaming,
// like Dolphin is trying to. That will likely never be able to reach the same speed as perfectly optimized
// superbuffers though. For this we will have to JIT the vertex decoder but that's not too hard.
//
// Now, when do we delete superbuffers? Maybe when half the buffers within have been killed?
//
// Another idea for GTA which switches textures a lot while not changing much other state is to use ES 3 Array
// textures, if they are the same size (even if they aren't, might be okay to simply resize the textures to match
// if they're just a multiple of 2 away) or something. Then we'd have to add a W texture coordinate to choose the
// texture within the bound texture array to the vertex data when merging into superbuffers.
//
// There are even more things to try. For games that do matrix palette skinning by quickly switching bones and
// just drawing a few triangles per call (NBA, FF:CC, Tekken 6 etc) we could even collect matrices, upload them
// all at once, writing matrix indices into the vertices in addition to the weights, and then doing a single
// draw call with specially generated shader to draw the whole mesh. This code will be seriously complex though.
