No easy way to retrieve Raw pixel formats

[rongcuid]

I use mostly high-level bindings everywhere in the program, and it is fine. Until I try to create a surface:

createRGBSurface :: (Functor m,MonadIO m)
                 => V2 CInt -- ^ The size of the surface
                 -> CInt -- ^ The bit-depth of the surface
                 -> V4 Word32 -- ^ The red, green, blue and alpha mask for the pixels
                 -> m Surface

I have no way to get the bit depth and mask information unless I either hard code them, or retrieve them from SDL.Raw.Types.PixelFormat. Reading the source code, I notice that there are two functions toNumber and fromNumber that converts the two. However, they are apparently not exported. Would it be a good idea to export them?

Appears to be fixed.
