Christophe CURIS f85066a19e wrlib: move fixed angle rotation code to dedicated functions ...

The function RRotateImage contains code to handle efficiently the 4 simple
angles 0, 90, 180 and 270 degrees, which makes it a long function.

This patch separate the code for the different cases into dedicated
functions so the main function's code ends up being simple (aka: easier to
understand/review/maintain).

As a side effect, the function for the 180 degree function is not static
because it can be reused to flip an image both horizontally and vertically.
