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.
All OpenGL related files are build as a kwinglutils library for OpenGL
and as a kwinglesutils library for OpenGL ES. The appropriate defines
are set using target_properties and removed from kwinconfig.h.cmake.
Removes the Extension::glxAvailable() from kwinglobals and
implements the functionality in CompositingPrefs, where it
is only needed. There used to be one additional check in
scene_opengl_glx.cpp which is moved into composite.cpp
before the OpenGL Scene is created.

I still don't understand how I actually tested my patch
before committing. It was working, sigh. That were
several hours of annoyance including a git bisect presenting
my own commit I assumed to be correct. Sigh.
If the environment variable KWIN_GL_DEBUG is set to 1
the define KWIN_SHADER_DEBUG is added to the glsl
source code allowing to add some custom ifdefed
visual debug handling.
As an example it's added to scene-fragment.glsl to
paint everything in a greenish way.
Construct window quads which will end on the screen instead of
rendering the windows several times and using scissoring to
restrict to the area which will end on screen.

Now convertToGLFormat does no longer mirror the texture, so that we can
avoid a deep copy in case we render a GL_BGRA texture on a little endian system.
