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