Christophe CURIS 3a15750ad5 WPrefs: add check for image validity in 'loadRImage' (Coverity #50221, #50081) ...

As pointed by Coverity, the function blindly trust the data read from the
file, but in case of problem (corrupted file, not enough memory) it could
behave badly.

This patch adds a check for the depth, counts on RCreateImage to check the
width and height, and in any case it now includes a message for the user in
case he would like to understand what's wrong.
