I would suggest to not use the assambler-like shaders but the OpenGL Shading 
Language supported from OpenGL 1.4 and newer. It is heavily based on C.

Documentation can be found here:
http://www.opengl.org/documentation/glsl/

I think we need vertex-shaders and fragment-shaders. This is usefull even in 
the case the code draws a single quadrangle for texturing it.

Vertex-shaders and Fragment-shaders are one unit - the vertex-shader has to 
set the variables which should be interpolated by the rastering stage of the 
pipline and passed to the fragment-shader.

Expamples for Texturing with GLSL can be found here:
