Since the funtionality of TopMenu did no longer work in KDE4 this feature was
removed from Workspace. Every reference to it was removed as well as commentaries
and documentation.

Without Compositing we do not really need the PaintRedirector,
it only adds overhead. This reverts the behavior to how it was before
the PaintRedirector was introduced by just not redirecting the paint
in the event filter when compositing is not active. This should have
the lowest impact on the existing source base.
The change breaks at least oxygen window decoration when compositing
is not active as the decoration is no longer double buffered. But
as written this is exactly the behavior as used before 4.3. Given
the push today there should be enough time for all affected decos
to adjust to the change.

Drawbound was nowadays only used when compositing is disabled.
For the composited case, the drawbound was replaced by the resize
effect and in fact we should always just use the resize effect.

Mouse Emulation is provided in a better way by KAccess. This provides
a global systemsettings switch to enable mouse emulation instead of
a shortcut and Xkb to enable mouse control with keyboard instead of
sending out fake mouse events.
So no need for duplicated functionality in KWin.

The uniforms textureWidth and textureHeight were only needed for
normal windows. For everything else it was just 1.0/1.0, that is
normalized.
The makeArrays method is changed to produce normalized texcoords
obsoleting the need for these uniforms. So two uniforms less, one
calculation in vertex shaders less and many many lines of code
removed.
At the same time makeArrays is also adjusted to take care of
yInverted of the texture, which is needed as we no longer can use
the enableUnnormalizedTexCoords which did the yInverted transformation.

While closing a window it might happen that we emit the windowOpacityChanged
signal although we dont have an EffectWindow.

by checking the graphicssystem at startup
also avoid pixmap and memory leaking on the xrender backend, validate some pointers
on deletion in SceneOpnGL and avoid attempts to render ::isNull pixmaps
Actually it's more a hack and should be addressed in the next
release cycle by allowing effects to modify the scene's blend
equation.

This was causing problems with R300G. The GPU supports only limited
GLSL and seems not to be up to rendering the scene appropriate. So
let's better disable the OpenGL 2 branch for such GPUs. If the user
really wants to use it, there is the GLES backend which does not
check for limited GLSL.

For what reason ever motion manager thinks that windows are not
moving during the start animation (but are during the stop animation).
So we also have to look on the timeline to decide whether we should
disable lanczos filter on the windows.
Now wonder the animation was stuttering.

The logic to prevent errornous desktops broke setting a window
to all desktops through the task manager. For some reason all
desktops is -1 which is of course less than 1 ;-)
In case we use OpenGL compositing and KWin is started with the raster graphicssystem,
the decoration gets painted with the raster backend.
