[AD] soft routines in draw.h

[Jon Rafkind <workmin@xxxxxxxxxx>]

In draw.h there are _soft_*() routines which implement various shapes in 
software, I presume. Things like:
AL_FUNC(void, _soft_circle, (struct BITMAP *bmp, int x, int y, int 
radius, int color));
AL_FUNC(void, _soft_circlefill, (struct BITMAP *bmp, int x, int y, int 
radius, int color));
AL_FUNC(void, _soft_triangle, (struct BITMAP *bmp, int x1, int y_1, int 
x2, int y2, int x3, int y3, int color));
AL_FUNC(void, _soft_polygon, (struct BITMAP *bmp, int vertices, AL_CONST 
int *points, int color));
AL_FUNC(void, _soft_rect, (struct BITMAP *bmp, int x1, int y_1, int x2, 
int y2, int color));

Does the user need to know about these functions in the sense that they 
are exposed in a public .h file? Can these be moved to a private_draw.h 
or something? I would appreciate this because I am writing interfaces to 
Allegro for other languages and its highly convienent to simply copy and 
paste functions from a .h file and transform them into the language I am 
interfacing with rather than figure out which functions I actually need 
from the .h file.

I assume there are other instances of these things in other files that 
could also be moved.
