This is used to figure out the size of "invisible" decorations, which we'll
use to better know the visible extents of the surface, which we can use for
constraining, titlebars, and more.
This makes button handling more correct concerning drags. Also,
frame_pointer_button returns the original button location in the case of a
release. This makes filtering of button events much easier for users of
the cair-util frame code.

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.
Fix the following build warnings, and the build failures due to the
warning fixes:
CC libshared_cairo_la-image-loader.lo
image-loader.c:369:1: warning: no previous prototype for 'load_image'
CC x11_backend_la-compositor-x11.lo
compositor-x11.c: In function 'x11_output_set_icon':
compositor-x11.c:396:2: warning: implicit declaration of function 'load_image'
compositor-x11.c:396:8: warning: assignment makes pointer from integer without a cast
CC wayland_backend_la-compositor-wayland.lo
compositor-wayland.c: In function 'create_border':
compositor-wayland.c:97:2: warning: implicit declaration of function 'load_image'
compositor-wayland.c:97:8: warning: assignment makes pointer from integer without a cast

We were pulling in cairo and the image loading libraries through libshared.
Split out libshared into a core libshared and a libshared-cairo that
pulls in the extra libraries.
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.
