Now look for 8 bits of alpha when the developer has requested
FL_RGB8 (STR #541)
The last line in an Fl_Help_View widget was not aligned properly
(STR #536)
The "search" symbol looked like a Q (STR #536)
Changed Fl_Help_View::get_color() to use a lookup table to avoid
serious Borland C++ 5.5 compiler bugs (STR #533)
Fixed Watcom compiler warnings with FL/Fl_Widget.H (STR #540)
The image class copy() methods did not always make a separate
copy of the image data (STR #539)
