Ha! Very good news! I hope to improve things in the long run but any
help is welcome :).
Next big goals are:
- rewrite nuiEditText to use nglFontLayout derived classes. (and
implement word wrap, justification... my be have better text handling
functions too)
- try again to enable partial widget/screen redraw. I had a working
implementation this summer but noticed that the nuiTopLevel widget had
to be implemented first in order to get this to work.
- implement new widgets and containers! (knobs, sliders, multistate
buttons, etc...).
- optims optims optims (even look at how we could gain some speed by
using some new 1.3 -> 1.5 and other exts features).
- Add scripting support (that'd be so cool). Preliminary look at this
have shown that LUA seems like the best bet but it might be possible to
implement a language agnostic scripting support layer.
- Better SVG rengering, anyone cares enough to start this project? ;)
- Better XML parsing.
- ... :)

Going from nglFont1 to nglFont have been quite a perf hit for nui.
Maybe we are not using it correctly and you could advise us after a
quick look at the code?
nuiLabel code looks alright. Maybe it would be simpler if the layout
was actually a non-dynamic member, but you could not change the font
in a single lifecycle of the widget. Maybe we could add font switching
in nglFontLayout (I remember I had one good reason not to do it, but
forgot it :)).
Otherwise, there is something really odd in nglFontBase : the
FreeType cache is set to 2KB! nglFontLayout::GetMetrics _will_ be slow
as hell since it will rasterize glyphs everytime. I must have
postponed this problem and set an horrible number to make sure it
would not be forgotten. Rats, missed.
I really don't know what number will do. Will depends on the target.
I'll put a good megabyte and wait for complaints about heavy memory
usage by nglFontBase. It's only a limit, it will eat less if you
require less (growing buffer).
Fix commited.
