FLTK 1.3 uses larger data types for some basic variables. Graphics coordinates are now 32 instead of 16 bits. UTF8 rendering should not have any impact for ASCII text. Only when massive amounts of glyphs are required for large fonts, initialisation may be slower than usual. There is one additional indirection for all graphics calls, but that is in todays CPU terms close to nothing. In return we get multiple rendering contexts, including printing. Other than that , the code is very similar. Can you specify what exactly seems slower now than it has been? _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
