Changed my mind on keeping GLES1 code alive... whole hog for GLES2.
Step 2 for VBOs.  Optimized/re-factored geom and geomData to make them work better for VBO, including making geomData a travDataCollection.

Also moved travData to be a hash map, which looking empirically at llvm’s stdlib, looks like it will be a good memory/speed tradeoff.
