Each effect is able to declare itself as currently being active,
that is transforming windows or painting or screen or doing anything
during the current rendered frame.
This change eliminates the hottest path inside KWin identified by
callgrind.

Effect uses framebuffer blit to copy the zoomed are in a scaled
way into an offscreen texture and render the texture after the
rendering. This means instead of two rendering passes we now need
only one pass, but require the blit extension.
Due to changes in build system we have always either OpenGL or OpenGL ES.
This allows to remove the KWIN_HAVE_OPENGL_COMPOSITING define. In the
effects the define is kept as KWIN_HAVE_OPENGL which can be used in
future to build also an XRender only effect system.

If we have OpenGL ES but not OpenGL the KWIN_HAVE_OPENGL is set
causing the first compile pass to fail as it tries to build
against OpenGL. As a solution the first pass links against
OpenGL ES if OpenGL is not found.
This means both kwin and kwin_gles are built against GLES.
Nuno has to decide whether the new option will become default or not, for now it is disabled by default.
You can enable it in effects kcm, now Login effect has a configuration dialog.
It does not (yet) however check for non-fullscreen effects, so they might look weird when this is enabled.

Reflection in a vertical multiscreen setup are kind of broken without
PaintClipper. But we have to ask ourselfe whether CoverSwitch in a
vertical multi screen setup makes sense and whether it's useful to
have reflections in such a setup.
Horizontal multiscreen setup works fine (also with reflections).
