/*
|
|
The base class for compositing, implementing shared functionality
|
|
between the OpenGL and XRender backends.
|
|
|
|
Design:
|
|
|
|
When compositing is turned on, XComposite extension is used to redirect
|
|
drawing of windows to pixmaps and XDamage extension is used to get informed
|
|
about damage (changes) to window contents. This code is mostly in composite.cpp .
|
|
|
|
Compositor::performCompositing() starts one painting pass. Painting is done
|
|
by painting the screen, which in turn paints every window. Painting can be affected
|
|
using effects, which are chained. E.g. painting a screen means that actually
|
|
paintScreen() of the first effect is called, which possibly does modifications
|
|
and calls next effect's paintScreen() and so on, until Scene::finalPaintScreen()
|
|
is called.
|
|
|
|
There are 3 phases of every paint (not necessarily done together):
|
|
The pre-paint phase, the paint phase and the post-paint phase.
|
|
|
|
The pre-paint phase is used to find out about how the painting will be actually
|
|
done (i.e. what the effects will do). For example when only a part of the screen
|
|
needs to be updated and no effect will do any transformation it is possible to use
|
|
an optimized paint function. How the painting will be done is controlled
|
|
by the mask argument, see PAINT_WINDOW_* and PAINT_SCREEN_* flags in scene.h .
|
|
For example an effect that decides to paint a normal windows as translucent
|
|
will need to modify the mask in its prePaintWindow() to include
|
|
the PAINT_WINDOW_TRANSLUCENT flag. The paintWindow() function will then get
|
|
the mask with this flag turned on and will also paint using transparency.
|
|
|
|
The paint pass does the actual painting, based on the information collected
|
|
using the pre-paint pass. After running through the effects' paintScreen()
|
|
either paintGenericScreen() or optimized paintSimpleScreen() are called.
|
|
Those call paintWindow() on windows (not necessarily all), possibly using
|
|
clipping to optimize performance and calling paintWindow() first with only
|
|
PAINT_WINDOW_OPAQUE to paint the opaque parts and then later
|
|
with PAINT_WINDOW_TRANSLUCENT to paint the transparent parts. Function
|
|
paintWindow() again goes through effects' paintWindow() until
|
|
finalPaintWindow() is called, which calls the window's performPaint() to
|
|
do the actual painting.
|
|
|
|
The post-paint can be used for cleanups and is also used for scheduling
|
|
repaints during the next painting pass for animations. Effects wanting to
|
|
repaint certain parts can manually damage them during post-paint and repaint
|
|
of these parts will be done during the next paint pass.
