Divide by div and return the remainder, from 0 to div-1. Standard long-division algorithm.

This function forces all GL state to be re-sent to the context. Some state will only be set on the next batch flush.

for boolean knobs..

Return the number of letters following the dot. Returns 4 if there is no dot. (So "r0.xy" returns 2 and "r0" returns 4).

This returns 0 for x, 1 for y, 2 for z, and 3 for w.

accessors for the started/stopped state

Return true if all elements of m_data are zero.

Replace the parameter name and leave the swizzle intact. So "somevar.xyz" becomes "othervar.xyz".

glUseProgram() will be called as a side effect!

This totally sucks, but this information can't be gleaned any other way when translating from D3D to GL at this level

If the register happens to end with ".xyzw", then this strips off the mask.
