-Rotates a 32-bit or 8-bit 'src' surface to newly created 'dst' surface.
-'angle' is the rotation in degrees, 'centerx' and 'centery' the rotation center. If 'smooth' is set
-then the destination 32-bit surface is anti-aliased. 8-bit surfaces must have a colorkey. 32-bit
-surfaces must have a 8888 layout with red, green, blue and alpha masks (any ordering goes).
-The blend mode of the 'src' surface has some effects on generation of the 'dst' surface: The NONE
-mode will set the BLEND mode on the 'dst' surface. The MOD mode either generates a white 'dst'
-surface and sets the colorkey or fills the it with the colorkey before copying the pixels.
-When using the NONE and MOD modes, color and alpha modulation must be applied before using this function.
-
-\param src The surface to rotozoom.
-\param angle The angle to rotate in degrees.
-\param centerx The horizontal coordinate of the center of rotation
-\param zoomy The vertical coordinate of the center of rotation
-\param smooth Antialiasing flag; set to SMOOTHING_ON to enable.
-\param flipx Set to 1 to flip the image horizontally
-\param flipy Set to 1 to flip the image vertically
-\param dstwidth The destination surface width
-\param dstheight The destination surface height
-\param cangle The angle cosine
-\param sangle The angle sine
-\return The new rotated surface.
