a protocol to activate the blur behind windows and to
optionally set a sub region of the window where to apply
the blur to, in case the window is shaped
REVIEW:125015
This implements the subcompositor and subsurface protocol on both
Client and Server side.
Client:
New classes SubCompositor and SubSurface. The SubCompositor can be
created through the Registry and creates the SubSurface which is
bound to a Surface and has a parent Surface. The SubSurface class
provides convenient wrappers for all calls exposed in the
wl_subsurface interface.
Server:
New classes SubCompositorInterface and SubSurfaceInterface. Support
for all commands is added, though the API probably still can need
some fine tuning. The synchronized vs. desynchronized behavior is
not yet exposed in the API. This could also be delegated towards
the user of the library.
The unit test found a few problems which are now addressed
* getBuffer did not check the format when reusing a buffer
* creatBuffer used the wrong method on QSize to check whether it is empty
* destroy didn't call destroy on the Buffer. This is now added by moving
the Buffer::Private in a dedicated header which can also be included
from the ShmPool
Framework style build system which generates two libraries:
* KF5WaylandClient
* KF5WaylandServer
autotests are adjusted to compile again. They need to be changed to
use the libraries once the export header gets generated.
