[SDL] SDL 1.3 image scaling

Well that's odd..  It looks like the code in D3D_RenderCopy actually supports 
different scale modes, but D3D_SetTextureScaleMode doesn't actually support 
*setting* the mode!  You ought to write up a patch for it.

Hi Folks

I'm scaling an image from 1024x768 to 1280x1024, and the result looks like a car 
crash. It's all pixellated and horrible, whereas if I scale it in Fireworks/GIMP 
etc it looks OK.

I see a comment that "SDL_TEXTURESCALEMODE_FAST is the only type supported at 
this time" and the SDL source seems to confirm it. 

Is there any way to get it better? I am using DirectX - what about GDI or 

Any help much appreciated!
