[SDL] "Free image transformation"

[Vardar Sahin]

Try to use the SGE lib
http://www.etek.chalmers.se/~e8cal1/sge/index.html

maybe this funktion can help you

*void sge_TexturedRect(SDL_Surface *dest, Sint16 x1, Sint16 y1, Sint16 x2,
Sint16 y2, Sint16 x3, Sint16 y3, Sint16 x4, Sint16 y4, SDL_Surface *source,
Sint16 sx1, Sint16 sy1, Sint16 sx2, Sint16 sy2, Sint16 sx3, Sint16 sy3,
Sint16 sx4, Sint16 sy4)*
Draws a texture mapped rectangle (p1,p2,p3,p4) on dest with the texture from
the rectangle (sp1,sp2,sp3,sp4) on src.
