- automatic picking of backends (discussed with Alex on IRC, he'll think a bit about it)
- SKIP tests without X server available (will look into using Xvfb and Wayland for it)</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;"><p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This patch adds a QScreen backend to libkscreen.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This is useful to avoid a dependency on XRandR (at build time) and a running X server at runtime.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The backend itself is read-only and kept simple. It only reports the basic necessities (which is what QScreen provides).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The changes are kept to the backends/qscreen directory, so no API has been touched. The changes outside of that directory are autotests, tests, and a fallback to the qscreen backend non non-X11 platforms. The latter will automatically make libkscreen work on Wayland (as far as QScreen allows us to, so r-o). This case otherwise just crashes, and the XRandR backend can't work. If the user specifies the backend using the KSCREEN_BACKEND env var, it will be respected, the automatism only triggers when no backend is explicitely specified. I've also added apidocs in some files, but again, no functional changes.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The plan is to augment this also with a native Wayland backend, which will take a bit longer to complete (more complex, it's r-w, I have to learn Wayland APIs). That backend is work-in-progress in the sebas/wayland branch. The QScreen backend allows us to test and run our code under Wayland, without crashing, so we can continue the port while a native Wayland backend is conceived.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">You can find the code for this QScreen backend in sebas/qscreen if you'd like to give it a try.</p></pre>
