KWin::Cursor can track changes to the cursor image. It supports a
start/stop tracking to not handle these events if nobody is interested in
them. When enabled and the cursor image changes a signal is emitted with
the serial number of the new cursor image.
To track cursor image changes xcb_xfixes_select_cursor_input is used (see
XFixes Version 5.0 protocol, section 7).
This could be useful for the zoom effect when it replaces the cursor.

This shortcut did not make any sense to me, because you could block the
global shortcuts for KWin, but not re-enable them again. So once blocked,
it was blocked for ever till kwin --replace &.
This is in opposite to the commit message which introduced it
(see BUG 108961).

* don't execute OpenGL test app if user selected XRender
* don't execute OpenGL test app if user forces to EGL
If a user selected XRender because OpenGL is failing badly it might not
be the best idea to call an OpenGL application.
If the user enforces EGL it's kind of pointless to call a testapp which
uses GLX.

Unfortunately only information available through the factory can be read.
As Factory is not a QObject we cannot use the Q_SLOT trick to get further
information dynamically from the loaded decoration plugin.

This was currently basically broken:
* Screen number got always attached
* openGLIsBroken did not check for screen number
-> KCM reported "everything is fine" while it wasn't
Now changed to:
* only attach screen number if it is a multi-head setup
* use same logic in both Composite and CompositingPrefs
Still problematic:
* kcm is not multi-head aware so it will report everything is fine in
case of a broken multi-head setup

Shader moved to 1.10 subdirectory and a new version for 1.40 added.
At the same time call to glPolygonMode removed as it caused errors with
core context (and seems to not be needed).
REVIEW: 110572
Shaders are moved into dedicated directories 1.10 and 1.40. 1.10 contains
the already existing versions, 1.40 copies of them adjusted to GLSL 1.40.
REVIEW: 110571
In case OpenGL ES 3 is provided by the driver we can use the GLSL 1.40
shaders as GLSL 300 ES shaders. The #version declarative is rewritten in
such a case.

Only the subset of functions available in core contexts is resolved,
except for glGetnTexImageARB() and glGetnUniformivARB(), which are
not used by kwin.
Instead of setting the function pointers to NULL when the extension isn't
supported, kwin provides its own implementations that call the non-robust
versions of the functions. This is so callers don't have to check if the
extension is supported before calling the functions.
We always reset with the complete window geometry, so the subtracting
doesn't make any sense. We can just always set the damage to an empty
region.

This changes the default refresh rate (which KWin uses if it cannot get the rate from the screen) from 50Hz to 60Hz.
There are two reasons for this:
- When plugging out the last active screen, even without calling xrandr the X server changes the screen geometry to some built-in minimum (320x200), with, of course, no information about the refresh rate. As a result, KWin assumes 50Hz and restarts the compositor to accommodate for this change, only to change it again soon thereafter when there's a screen again.
- I know of nobody using a 50Hz screen. Most people use 60Hz, some use 120Hz, but 50Hz seems pretty rare to me.

required because Screens::changed is emitted queued in case of timer shortcut
since a direct signal would cause problems on screen resizes (or rotations,
for that matter) since at that time QDesktopWidget::screenGeometry(int) -xrandr-
is updated, but QDesktopWidget::screen(int)->geometry() (root window) is NOT,
resulting in an invalid value in geometry.cpp/Workspace::desktopResiized(),
thus a "capped" overlay window
However, w/o the count updated we re-encounter what RR 110119 was supposed to fixed
in the first place ...

FIXED-IN: 4.11
The CM selecton withdraw delay was introduced to mostly unburden
plasma from recreating the theme on temporary changes, but since
plasma also watches some properties hinting supported features
and acts in consequence, this isn't sufficient and actually causes
two theme changes instead of one in the case of a regular suspend

stealing it from ourself is reported to be able
to confuse KWindowSystem about the state.
Also it causes minor but unnecessary overhead.
