Merge branch 'master' into temp-explicit-colors

Performance: GPU Batch Baseline TestCase.

When using a dense mesh and transforming a small number of verts the mesh received a copy-on-write signal. This will free all GPU batches. No reuse is currently possible.
This patch adds a test case that can be used as a baseline to optimize the cache construction in the draw module.
