2007-03-08Rework matrix-related code.Brian
GLSL matrices are stored in column-major order while GL_ARB_vertex/fragment_program use row-major. So, need to use STATE_MATRIX_TRANSPOSE for built-in matrices. Unfortunately, this means that the expression M * V isn't very efficient since we need to extract the rows out of M. And that's the typical expression for vertex transformation: gl_ModelViewProjectionMatrix * gl_Position. Solve this inefficiency by looking for M*V expressions and replacing them with V*Transpose(M). Also, add support for GLSL 1.20's MatrixTranspose, Inverse and InverseTranspose matrices.

2007-01-17Rewrite a bunch of constructors. It's now important that the firstBrian
constructor for any given type be the one that takes the most parameters as this is the constructor that'll be used when there's no perfect match to the caller's arguments. See the _slang_adapt_call() function for details.

2007-01-15Reimplement the post-increment/decrement functions.Brian
Instead of defining functions with an extra dummy parameter to distinguish from the pre-incr/decr functions, just use new function names: __postIncr and __postDecr.
