* modules/macosx/{vout,voutqt}.m: The Mac OS X Mozilla plugin lives again!
Some details:
* This was mostly taken verbatim from revision:5717 (before the vout
Mozilla support was removed), though it's been edited pretty thoroughly,
and is now much more commented.
* The "normal" vout display should be completely unaffected, since the
plugin-relevant code paths are only taken when p_vout->p_sys->b_embedded is
set to VLC_TRUE. (I've tested the normal VLC.app, and it seems fine.)
* There are still some problems with the plugin when the Mozilla window is
resized a lot. I suspect this is due to threading issues with
QuickDraw, but I don't know enough about QuickDraw to be sure. Help
with this would be very welcome.
* The original patch in revision:5717 optimised the plugin display
slightly, by using a mask (clipping region) so that QuickDraw only
updated the plugin's area of the dirty region. I elected not to use
a mask, since I thought the extra code complexity (i.e. lots more if()
branches) isn't worth the incremental speedup. (If, in fact, there was
a speedup at all -- the extra overhead induced by calculating the
intersection of the dirty region with the mask may have offset any
benefits: only benchmarks will tell ...)
