6641ac5648 GLRenderBuffer supports legacy painting if VBOs are not available. 
This gives us one API for both legacy and modern painting.
All glRenderGeometry* calls are deprecated as they use quads and
legacy painting.

b296b7a00c Generate correct tex coordinates for rendering a texture. 
This way we can get rid of the texture matrix transformations when rendering a standard texture - no matter if it's inverted or not.

cf3bcc6294 Try to get a FBO in the init method of GLRenderTarget. If the FBO is incomplete there is no need to claim that the driver supports FBO. 
This is a workaround to the problem that some drivers do not return a complete FBO, but support the extension. Which caused the blur effect to get loaded without working and in consequence Plasma to use the blur-optimized and very translucent backgrounds.

7e68fc7c44 Use GL_BGRA instead of GL_RGBA when creating textures. 
GL_BGRA is the native format, and should be faster since it doesn't
require any internal swizzling.

d7665af4f0 Texture width and height is stored in GLShader and the uniform value is set during prepareShaderRenderStates in scene_opengl. So the effects do not have to set the uniform manually. This is useful as other effects can still set this uniform if something different is rendered with a different texture width/height (e.g. shadows or thumbnails). When the window is finally rendered the original value set by the effect is definatelly used. 
First effect to use this new way to set texture width and height is invert effect.

d69942d215 Reverted the text part of the previous commit, seems the bug is in Qt 
(Premultiplied text painting on a non-premultiplied QImage). Fixed text
color of frameless and unstyled frames when using a Plasma theme that
has a non-white primary text color. Updated
GLTexture::convertToGLFormat() to use the latest version from Qt.

bb433ac40e No longer include config*.h files in installed headers. 
Also slightly redo the #define's for effects, now it's:
- #ifdef KWIN_HAVE_COMPOSITING to check whether there's any compositing support at all
- #ifdef KWIN_HAVE_OPENGL_COMPOSITING to check for OpenGL-based compositing
- #ifdef KWIN_HAVE_XRENDER_COMPOSITING the same for XRender

424f906ab2 - Add optional color argument to renderGLGeometry() functions. If specified, it's used as vertex colors 
array when rendering.
- Rearrange some renderGLGeometry() parameters.
- Don't use opengl arrays and glDrawArrays() when rendering a small number of vertices since in this
  case overhead of enabling/disabling the array is too big. Use immediate mode instead in such case.

a94aa904b0 Well, actually GLRenderTarget doesn't require NPOT textures (it works with rectangle textures as well). 
That also means that those effects which do require NPOT have to check for it themselves.

Liquid demo effect now sets wrap mode to CLAMP to ensure that the texture won't wrap at edges
