fb57ce17ef shared/cairo-util: Release any fontmap laying around
This is particularly useful when using the weston-editor which seems to
cause an issue with cairo_debug_reset_static_data(), as that still seems
to find out there are references laying around, causing a crash when
exiting:

cfe35b591f shared/cairo-util: Re-use the PangoContext for layout creation
Rather than creating a new PangoContext each time the menu redraw
handler is triggered re-use it if one was created previously.

All toytoolkit clients do create a layout (and implicitly a
PangoContext) but only those that have menu redraw
handler installed will create a new layout for each redraw of the menu,
effectively creating a new PangoContext each time.

c55a14206d cairo-util: Clean up more Cairo detritus; almost all of it
Pango, Cairo, and fontconfig, all want to leave thread-global data
hanging around in order to maintain a cache. Try to clean up as much of
it as we possibly can on exit, apart from the Pango language string
which appears to be unfreeable, so has been added to LSan suppressions.

2afb812d1e shared/cairo-util: Hold onto our pattern reference until we're done
This doesn't actually fix a bug - cairo refcounts this. But I
really don't like the look of code that drops a reference then
continues to use it.

While we're here, set a different pattern when we're done so the
one we allocated loses its last reference.

The title in X11 windows and Wayland application using Weston toy
toolkit were placing the title in a very naive fashion. It was
only try to center the string in the title bar. This patch:

 * Makes sure the title isn't renderer underneath buttons;
 * Move the title to the left if the titlebar isn't large enough;
 * Clip the end of the title if needed.

eaea470510 cairo-util: fix shadows for small clients
If the client is small (< 128 pixels in any ward),
then the shadows overlap and create dark lines behind clients.
This is a problem mosly with pop-up menues. The lines become observable
when the menu has less than three items. The other case is when
the client doesn't restrict its size when resizing (try
'weston-eventdemo --max-width=1 --max-height=1' for example)

This fixes a part of the bug:
https://bugs.freedesktop.org/show_bug.cgi?id=78511

v2:
  - rework computing of the size of corners
  - rewrite some comments
  - rename tile_mask to render_shadow (in separate patch)

c228e23b05 configure.ac: Enable AC_USE_SYSTEM_EXTENSIONS
AC_USE_SYSTEM_EXTENSIONS enables _XOPEN_SOURCE, _GNU_SOURCE and similar
macros to expose the largest extent of functionality supported by the
underlying system.  This is required since these macros are often
limiting rather than merely additive, e.g. _XOPEN_SOURCE will actually
on some systems hide declarations which are not part of the X/Open spec.

Since this goes into config.h rather than the command line, ensure all
source is consistently including config.h before anything else,
including system libraries.  This doesn't need to be guarded by a
HAVE_CONFIG_H ifdef, which was only ever a hangover from the X.Org
modular transition.

3c2360ff9d Add new shared/image-loader.h to separate include dependencies
Before, cairo-util.h would combine pixman and cairo includes.  X11 and
Wayland compositors uses this to load an image as a pixman_image_t but are
forced to include cairo headers.  Clients use load_cairo_surface to
load images as cairo_surface_t's, but are forced to include pixman.h.

We move the load_image pixman prototype to its own header, so compositors
can get at the pixman prototype without including cairo.h and clients
can include the cairo based function without including pixman.h.
