As pointed by Coverity, there might be some problems due to sign extension when performing the shifts and ors operations when converting the RImage to the format expected for the WM_ICON property. This patch try to improve things by using as much as possible unsigned types and by using explicit types conversion instead of counting on the wrong implicit type conversion done by the language.
