GLES1: Optimize texcoord varyings Use vec3 instead of vec4. Either 2 or 3 components are used based on 2D or cube map textures. On hardware that can pack the varyings, this can reduce pressure on varyings. Additionally, this is a minor optimization to texture coord calculation (when !draw_texture) as one row of the 4x4 matrix multiplication doesn't need calculation.
