2007-03-12Implement GL_ARB_texture_rectangle supportBrian
This includes the sampler2DRect and sampler2DRectShadow types and the texture2DRect(), texture2DRectProj(), etc. built-in functions.
2007-03-12Add array bounds checking, fix memleaks, add null ptr checks.Brian
2007-03-11add NULL ptr checkBrian
2007-03-11Implement support for GL_ARB_draw_buffers with GL_MAX_DRAW_BUFFERS > 1.Brian
GL_MAX_DRAW_BUFFERS is currently 4. Added gl_FragData[] output for fragment programs. In _swrast_write_rgba_span() loop over the color outputs/renderbuffers.
2007-03-10Implement gl_FrontFacing for fragment shaders.Brian
For the time being, we put the gl_FrontFacing value in the FOGC.Y input register. Combining FOGC and FrontFacing in one register is a bit of a hack and may need to be changed someday.

2007-03-08added missing bvec2/3/4 constructorsBrian
2007-03-08fix broken vec4_seq, vec4_sne instructionsBrian
2007-03-08Update lessThan(), lessThanEqual() functions, improve some matrix constructors.Brian
2007-03-08Added IR_SLE and IR_SLT for <= and < operations.Brian
Using IR_SGE and IR_SGT with transposed args doesn't work since the __asm calls don't do argument matching by name, but by position. This fixes the broken lessThan() and lessThanEqual() functions.

2007-03-08check for attempted writes to read-only varsBrian
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.
