This patch changes the behavior of strictly bound textures such that
they are only updated if the corresponding window has been damaged.
Additionally GLTexture now keeps track of the current filter and
wrapmode setting.

Property invokes virtual methods returning false by default. Deleted
reimplements the isDeleted and returns true. Client returns true for
isClient. Method is not called isManaged as this is already used
inside Client.
If possible use the property to Toplevel or Client instead of the
pure virtual methods. This makes it easier to get a stable ABI.
Adding new methods to the class no longer requires to add a pure
virtual method.
From a performance point of view this change should not matter.
Most EffectWindow methods are not invoked during the repaint chain.
But only in response to an event like a window got added. There the
overhead does not really matter as well the previous implementation
made strong use of dynamic casts which are also not knwon for being
very fast.
This patch reduces the number of QRegion and WindowQuadList operations
by drawing the opaque and translucent parts of the window within the
same bottom to top pass.

There seems to be a problem with nouveau GLES if you want to create an
EGLImageKHR more than once in a frame for the same pixmap. This patch
circumvents the problem in the way that it implements tfp the same way
as the mesa example in
mesa/demos/src/egl/opengles1/texture_from_pixmap.c does it. A nice
side effect of this is that it also avoids the overhead of recreating
the texture for every damaged window.

The EGL path had no support for presenting sub-regions of the screen, we can
leverage EGL_NV_post_sub_buffer for that. This wouldn't be a win if we didn't
have to opt-out of flipping.

EGL_KHR_image is a functional superset of both EGL_KHR_image_base and
EGL_KHR_image_pixmap, which were split off later to allow the former to be
more modular. Older drivers might only expose EGL_KHR_image if they were
released before the split happened.

Fixes rendering issues with R300 and similar GPUs. If the texture
uses GL_TEXTURE_RECTANGLE_ARB as target the tex coordinates need
to be adjusted. This at least fixes missing text on EffectFrames
with graphicssystem native on R300. Hopefully more issues are
resolved by the change.

This patch adds an optional texture cache to the blur effect such that damaged windows in
front of the blurred region dont trigger a repaint of the whole blurred region which pretty
often results in a avalanche repaint of nearly the whole screen.

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.

Additionally:
- hide the GLTexture implementation using dpointers
- drop the unused function SceneOpenGL::Texture::optimizeBindDamage()
- Texture::load now loads a new texture and does not update the existing one

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.
Building the workspaces requires to have all the build dependencies
which were required for KWIN_HAVE_COMPOSITING to be set. This allows
us to remove all the ifdefs for this and gives us a cleaner code.

if both the GLES and EGL libs and headers are found.
Fold all the includes and libraries into 1 varaible each and use those.
in other words, you need to have both OpenGLES and EGL to do a successful build.
Fixes a major regression which allowed OpenGL
compositing to be used with software rasterizer, which
either did not work or crashed directly.
Cherry-picked from cf2f572 in branch KDE/4.7.
