e61ecff9b9 Check that getting compositing pixmap of a window succeeded. 
It may fail (or "fail") if the window is not mapped or if the geometry
doesn't match, both of which may happen due to the asynchronous
nature of X.

8299541652 Add build checks for XComposite, XDamage, XRender, OpenGL, and XShm. 
KWin should now build and run with/without any or all of the above.

f060c3bfbb Improved filtering algorithm. Now fast filtering is used by default, while (depending on SmoothScale in kwinrc) bilinear filtering is used on transformed windows and screens. 
Optionally, if SmoothScale is set to 2, trilinear filtering will be attempted instead of bilinear.  This requires GL_ARB_texture_non_power_of_two, GL_EXT_framebuffer_object, and valid mipmaps.

8fe5ec7709 Use glXGetFBConfigs instead of glXChooseFBConfig. 
This makes texture_from_pixmap mode work in more places.

  the window, e.g. for wobble effect

is enough.

9d25cf5166 SHM mode, using MIT-SHM extension for Pixmap->image data conversions

340e64ab51 With the overlay fix double-buffering now works too. 
Also dump drawing directly into the root window, OpenGL normally
clips the root window, so nothing is drawn. NVidia has "DisableGLXRootClipping",
but there's no way to detect that and there's still the non-db mode.
