Christophe CURIS cd29983e03 wrlib: do not create an alpha channel if the original image did not have it in RFlipImage ...

As it does not cost anything in the current code to not add this channel,
it is then probably a good idea to keep the output image with the same
format as the input image, this avoid wasting +33% of memory for something
that may be at best unused and at worst will induce extra cost when
manipulating the image.
