Copy an existing surface to a new surface of the specified format.
This function is used to optimize images for faster* repeat* blitting. This
is accomplished by converting the original and storing the result as a new
surface. The new, optimized surface can then be used as the source for
future blits, making them faster.
If you are converting to an indexed surface and want to map colors to a
palette, you can use SDL_ConvertSurfaceAndColorspace() instead.
If the original surface has alternate images, the new surface will have a
reference to them as well.
