LibGL: Fix GL_TRIANGLE_STRIP rendering only half its triangles
...
According to the documentation, we should switch around vertices every
other triangle to prevent front-face culling from removing them.
This allows Tux in Tux Racer to render correctly.

LibGL+LibSoftGPU: Add method to query device info
...
This adds a method `info()` to SoftGPU that returns the name of the
hardware vendor and device name, as well as the number of texture untis.
LibGL uses the returned texture unit count to initialize its internal
texture unit array.

LibGL+LibSoftGPU: Use device samplers for rendering
...
We now sample textures from the device owned image samplers.
Passing of enabled texture units has been simplified by only passing a
list of texture unit indices.
