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 ...

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.

When the scripting KCM triggered a loading of a script it did not work
because the scripting code was operating on an old data set.
Reparsing the configuration before evaluating which scripts to (un)load
solves this problem.

Allocate enough space to hold the geometry for multiple draw calls,
and use glMapBufferRange() to gradually fill the buffer. Once the
data store is full, it's orphaned and a new one is allocated.
Store the vertex positions and texture coordinates in the same buffer
object. This saves one buffer allocation in every setData() call.
The attributes are also interleaved as they are uploaded into the buffer
to maximize locality of reference.
