[patch] Remove pangocairo from Gtk+ 2.8.20

- Subject: [patch] Remove pangocairo from Gtk+ 2.8.20
- Date: Thu, 19 Oct 2006 15:04:46 -0500
Hi,
Attached is a patch against gtk+-2.8.20 CVS which replaces the
pangocairo text rendering with the old pangoxft code from 2.6. It
targets embedded systems which currently suffer some performance
bottlenecks using Cairo for text.
Note that in a few cases some fields of structures (e.g.,
_GdkGCX11.fg_picture and _GdkGCX11.fg_picture_color) had to be
re-added. This was done mainly because the restored pangoxft code used
them to calculate things. I'd gladly accept criticism about betters
ways to fetch the information using normal 2.8 internal state rather
than re-add those fields.
gdk_screen_get_font_options() and gdk_screen_set_font_options() also
don't do anything now. I'm not so sure how much a problem this is in
practice.
Using Manu Cornet's gtk-theme-torturer on some ARM hardware, 2.8.20
originally took about 55% longer than 2.6.10 to complete the GtkLabel
run. After these patches, it takes only about 8-10% longer than
2.6.10.
Thoughts?
