Martin Gräßlin	2e888da70e	[backends/virtual] Move save screenshot functionality to the backend ... Allows code reusability when adding an OpenGL backend.	2015-10-08 15:53:03 +02:00
Martin Gräßlin	bfa9646d1d	[wayland] Add a virtual framebuffer backend ... A new backend which doesn't present the rendered output. It uses a QPainter scene, renders to a QImage but doesn't present it anywhere. Thus a real virtual backend. By exporting the environment variable KWIN_WAYLAND_VIRTUAL_SCREENSHOTS the backend creates a temporary dir, prints the path to std-out and saves each rendered frame into that directory. Of course with exit it will be deleted again.	2015-10-02 10:58:33 +02:00
