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:

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

This function is used and clearly designed only for drawing the shadows.
Rename it so that it has name after what it does and also move some
common code into the function.

Previously geometry was changed to leave space for titlebar if a frame
has only buttons but no title. This patch fixes theme_render_frame to
avoid transparent titlebar.

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.

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.
Add THEME_FRAME_MAXIMIZED flag so the theming system can know not to draw
shadows for maximized windows. This allows maximized surfaces' content to be
sized and placed in a more expectable fashion.
