util-basic-vertex-shader

Contains a simple vertex shader that takes a vertex with a single float2 value in the range [0..1] (where (0, 0) is the upper-left coordinate of the quad) and outputs a position value with x, y in range [-1..1], a z value of 0, and a w value of 1, as well as a texture coordinate value in the range [0..1].

The way this shader is specified is platform-specific, and so the best reference is to actually refer to the shader itself.

This can be used as the vertex shader for every Cathode Retro pixel/fragment shader.
