WebGL 1 hardware acceleration tests

Working with WebGL in virtual machines can be hit or miss with hardware acceleration, especially WebGL 2. These tests provide a quick verification that at least WebGL 1 hardware acceleration is enabled:

1. To see what WebGL renderer you've got: WebGL Report (WebGL1 is first tab)

2. For a quick test of 3D acceleration: WebGL1 Water

3. For more extensive tests: Three.js WebGL1 (r152) examples
