We're about to add Direct3D support, where shaders are written in HLSL. Rather than write shaders twice (or more), convert them to a GLSL variant understood by the glslcc cross-compiler and generate the OpenGL ES 2.0 and HLSL variants. The HLSL is used by a future change. Signed-off-by: Elias Naur <mail@eliasnaur.com>
