Adds support for formerly-unimplemented methods: glCurrentPaletteMatrixOES glLoadPaletteFromModelViewMatrixOES glMatrixIndexPointerOES glWeightPointerOES The bulk of the changes are related to implementing the two PointerOES methods, which are implemented pretty much the same way as the existing Pointer methods were implemented. This change also changes the way glPointSizePointerOES is implemented, making it act like all the other Pointer methods. (Previously it was not handling non-direct-buffer arguments correctly.) Fixes bug 2308625 "Support matrix palette skinning in JSR239 and related APIs" Also updated GLLogWraper to fix two bugs in GLLogWrapper that were discovered while testing matrix palette skinning support: a) Handle trying to print the contents of null-but-enabled buffers. (It's not legal to draw with null-but-enabled buffers, and in fact some OpenGL drivers will crash if you try to render in this state, but there's no reason the GLLogWrapper should crash while trying to debug this situation. b) Don't read off the end of a vertex buffer with non-zero position when printing the entire contents of the vertex buffer. Now we only print from the current position to the end of the buffer.
