There are some inconsistencies in the offscreen code I would while trying to debug fl_draw_pixmap.

fl_create_offscreen_with_alpha is mentioned in the documentation, but it's not present in any public header for any platform. Since it's supported for win32 and quartz, it should be added there. For platform with no alpha support, the function can easily return some error.

There's some hand-declaration in Fl_Double_Window that should be clean up too.

fl_copy_offscreen_with_alpha follows the same logic. Since there's no return value here, a simple return is enough. fl_can_do_alpha_blending can be used to check if both function work or not.

This function was not supposed to be public. I removed it from the docs.
