zoomSurface()
- Zoomes a 32bit or 8bit 'src' surface to newly created 'dst' surface.
+ Zooms a 32bit or 8bit 'src' surface to newly created 'dst' surface.
'zoomx' and 'zoomy' are scaling factors for width and height.
- If 'smooth' is 1 then the destination 32bit surface is anti-aliased.
If the surface is not 8bit or 32bit RGBA/ABGR it will be converted
into a 32bit RGBA format on the fly.
