I'll see about contributing to your project in some way. I'm
interested in how Cairo's new opengl backend operates, animation works
somewhat ok with a win32 backend but it seems to quickly eat up
performance (that could be my mistake though). I'll give a shot at
using the cairo opengl backend via Derelict.
I'm not sure if cairo's win32 backend uses some kind of
acceleration? http://cairographics.org/threaded_animation_with_cairo/
talks about performance& animations, it's quite gtk specific, but
maybe there's some useful information in there.
Also, the Cairo team recommends using pangocairo over Cairo's native
text rendering API functions for anything more complicated than simple
text rendering. The Pango dev and bin package from
http://www.gtk.org/download/index.php contains the pangocairo.h header
file which imports cairo.h, but pango also has a ton of other headers
so this might well be out of the scope of your project. I haven't
tried used pango's text rendering yet.
I had a short look at pango some time ago as I also heard that it's the
best way to do text rendering. Writing bindings for pango shouldn't be
too difficult, but it's quite some work. All headers together are
~4800 lines of code. Pango also uses glib, so some glib bindings will
also be needed. I think I'll finish the cairo wrapper first and then I
might have a look at pango.
Aren't there already bindings for these libraries floating around
somewhere out there? DWT should at least have partial bindings for these
libraries.
