Nunuhara Cabbage 81455baeb4 Implement more DrawGraph/SACT2 functions 
5 functions:

    SACT2.SP_SetDrawMethod
    DrawGraph.CopyStretch
    DrawGraph.CopyStretchAmap
    DrawGraph.CopyReduce
    DrawGraph.CopyReduceAmap

SP_SetDrawMethod is not pixel-perfect to System40.exe, but its pretty
close.

I'm not sure what the difference between the Stretch/Reduce functions is
supposed to be. They seem to do the same thing.

Also, the ugly macros in sdl_draw.c are replaced by higher-order
functions.

With this commit, Sengoku Rance runs up to the menu without exiting due
to unimplemented HLL functions.

Nunuhara Cabbage 766f93407b Implement the DrawGraph.Copy* family of functions 
Implement all of the simple copy functions, with the exception of
DrawGraph.CopyColorReverse, which is undocumented and appears to be dead
code (at least in the version of SACT2 that shipped with the SDK).
