Modified the tests to change GL state in the GL thread. GVRSceneMaker
now synchronizes scene construction and modification. This fixes several
intermittent failures with the texturing and render mode tests.
Fixed sphere construction in texture test.
Moved stress tests to their own section.
Made a new section for MeshTests. Collected the mesh tests from other
sections.
Moved rendering tests out of MiscTests into RenderConfigTests.
Fixed bounding volume test comparison logic
