* D3D / OPENGL compatibility notes:
* ---------------------------------
*
* To make your program compatible with D3D and OPENGL nel drivers, please follow thoses directives to write your vertex programs
*
* - Use only v[0], v[1] etc.. syntax for input registers. Don't use v0, v1 or v[OPOS] etc..
* - Use only c[0], c[1] etc.. syntax for constant registers. Don't use c0, c1 etc..
* - Use only o[HPOS], o[COL0] etc.. syntax for output registers. Don't use oPos, oD0 etc..
* - Use only uppercase for registers R1, R2 etc.. Don't use lowercase r1, r2 etc..
* - Use a semicolon to delineate instructions.
* - Use ARL instruction to load the adress register and not MOV.
* - Don't use the NOP instruction.
* - Don't use macros.
*
* -> Thoses programs work without any change under OpenGL.
* -> Direct3D driver implementation will have to modify the syntax on the fly before the setup like this:
* - "v[0]" must be changed in "v0" etc..
* - "o[HPOS]" must be changed in oPos etc..
* - Semicolon must be changed in line return character.
* - ARL instruction must be changed in MOV.
*
* Behaviour of LOG may change depending on implementation: You can only expect to have dest.z = log2(abs(src.w)).
* LIT may or may not clamp the specular exponent to [-128, 128] (not done when EXT_vertex_shader is used for example ..)
*
* Depending on the implementation, some optimizations can be achieved by masking the unused output values of instructions
* as LIT, EXPP ..
