This time with more manual checking and using git blame -M -C, so that
a few cases of copied code get a copyright notice corresponding to
their initial introduction.
Apart from these functions just being small enough to reasonably
inline, the compiler might be able to optimize parts of them away based on
knowledge of the type of the new or old content of the C4Value.
On at least one artificial benchmark, this does help significantly.
Instead of sprinkling calls to select the right context throughout the code,
store the context to use in the CSurface, and create a CSurface for every
window that's drawn to, and use that as the target parameter for the drawing
calls. D3D is probably even more broken now, but it should work just fine with
the right surface creation incantation.
