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.
We want to make sure that the matrix symbols are exported from weston and
that modules get them from there. To do that, we pull matrix.[ch] out of
libshared and back into weston. calibrator now also links to matrix.[ch]
and we add a IN_WESTON define to enable the WL_EXPORT macro when compiled
inside weston.
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.
On one hand, getopt (in particular the -o suboption syntax) sucks on the
server side, and on the client side we would like to avoid the glib
dependency. We can roll out own option parser and solve both problems
and save a few lines of code total.
Eventually we will want more functionality in the shared library and we
will rename it at that point. Perhaps we'll name it libnih, but for now
let's stick with libconfig-parser.
Create a new directory for convenience librariers that can be shared
between compositor components and clients.
