25 * D3D shader asm has swizzles on source parameters, and write masks for
26 * destination parameters. GLSL uses swizzles for both. The result of this is
27 * that for example "mov dst.xw, src.zyxw" becomes "dst.xw = src.zw" in GLSL.
28 * Ie, to generate a proper GLSL source swizzle, we need to take the D3D write
29 * mask for the destination parameter into account.

7029 * - This currently depends on GL fixed function functions to set things
7030 * like light parameters. Ideally we'd use regular uniforms for that.
7031 * - In part because of the previous point, much of this is modelled after
7032 * GL fixed function, and has much of the same limitations. For example,
7033 * D3D spot lights are slightly different from GL spot lights.
7034 * - We can now implement drawing transformed vertices using the GLSL pipe,
7035 * instead of using the immediate mode fallback.
7036 * - Similarly, we don't need the fallback for certain combinations of
