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 4eb5a256fd Refactor graphics code 
Sprites are now rendered directly, rather than being blitted to a master
surface which is then copied to a texture. Every sprite now carries an
SDL_Texture in addition to an SDL_Surface (we need both, since
SDL_Texture doesn't give read-access to the pixel data).

All of the image-manipulation code is now in sdl_draw.c, and the
DrawGraph_* functions are now wrappers. Some games (Daibanchou at least)
use an API other than SACT2/DrawGraph, so these operations should be
generic to avoid duplication.

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).

properly.
