<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">purpose:
- allow easier debugging
- for some backends (qscreen, upcoming kwayland) the out of process operation is not necessary since these backends are well-shielded</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This implementation is backwards compatible and opt-in for running setups.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">If the user exports KSCREEN_BACKEND_INPROCESS=1 before running, all operations will be done in process. Otherwise, the out-of-process mode is used.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Changes revolve around the ConfigOperations, the BackendManager (which "factories" the backends, either in- or out-of-process), and the plugin loading logic</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Autotests should cover all the cases (and actually a few currently unsupported ones, such as using different backends in the same process).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Details on performance, etc.: http://vizzzion.org/blog/2015/11/wayland-and-libkscreen-benchmarks/</p></pre>
