-<p>[RGBA]mask are the bitmasks used to extract that colour from a pixel.
-For instance, Rmask being FF000000 means the red data is stored in the most significant byte.
-Using zeros for the RGB masks sets a default value, based on the depth. (e.g. SDL::create_RGB_surface(flags,w,h,32,0,0,0,0);).
-However, using zero for the Amask results in an Amask of 0.
-It returns a SDL::Surface on success or undef on error.
-Notes: If an alpha-channel is specified (that is, if Amask is nonzero), then the SDL_SRCALPHA flag is automatically set.
-You may remove this flag by calling SDL::set_alpha after surface creation.
-Also, if the SDL_HWSURFACE flag is set on the returned surface, its format might not match the requested format. </p>
-<p>Notes: Sometimes specifying an Alpha mask value could cause strange results.
-This can be worked around by setting the Amask parameter to 0, but still including the SDL_SRCALPHA flag, and then using SDL::set_alpha,
-also with the SDL_SRCALPHA flag. </p>
