Important!

The clipping rectangle set by SDL_SetClipRect() will always be respected.
These functions will lock the surface if necessary, but you can control this with sge_Lock_ON/OFF().
The destination surface will be updated if necessary, but you should really do this yourself to avoid unnecessary updates; control this with sge_Update_ON/OFF().
Most drawing primitives can blend with the background; use the Alpha version of the routine to do this.
A few primitives also has an anti-aliasing mode; use the AA version of the routine to get this feature.

void sge_FadedLine(SDL_Surface *dest, Sint16 x1, Sint16 x2, Sint16 y, Uint8 r1, Uint8 g1, Uint8 b1, Uint8 r2, Uint8 g2, Uint8 b2)
Draws a horizontal line from (x1,y) to (x2,y) with its color faded from (r1,g1,b1) to (r2,g2,b2).

void sge_TexturedLine(SDL_Surface *dest, Sint16 x1, Sint16 x2, Sint16 y, SDL_Surface *source, Sint16 sx1, Sint16 sy1, Sint16 sx2, Sint16 sy2)
Draws a horizontal line from (x1,y) to (x2,y) on dest with the texture from the line (sx1,sy1) to (sx2,sy2) in src.
