Martin Gräßlin b8cc10ffab [kwinglutils] Improve cleanup handling
* add static cleanup handlers to GLTexturePrivate and GLRenderTarget
* revert the runtime resolved features (e.g. RenderTargets are not
  supported once we run the cleanup code)
* clear the extension lists
* reset the version variables

Martin Gräßlin c7d986c7fe [kwin] Remove the legacy OpenGL 1 compositing backend
KWin already has a de facto OpenGL 2 dependency through QML. Combined
with the fact that the OpenGL 1 backend is basically unmaintained and
also unused, it's better to remove it for the new major release.

This change includes:
 * Removal of cmake option KWIN_BUILD_OPENGL_1_COMPOSITING
 * Removal of KWIN_HAVE_OPENGL_1 compile option and all code
   ifdef'ed with it (partially removal of if-else constructs)
 * Removal of CompositingType::OpenGL1Compositing (flags are kept
   as a core flag should get introduced)
 * Driver recommendation for OpenGL1Compositing changed to XRender
   (should be evaluated whether the drivers can provide GL2)
 * Removal of configuration option "GLLegacy"
 * Removal of fooMatrix function in kwinglutils
 * Removal of ARBBlurShader
 * Removal of legacy code path in GLVertexBuffer
 * Removal of GLShaderManager::disable
 * if-blocks with ShaderManager::instance()->isValid() removed

Martin Gräßlin 5a521c149f Add GLTexture(const QSize &) ctor
Thanks to delegating ctors that's quite easy to do without boilerplate
code any more.

Thomas Lübking 3f5ef10c8e introduce GLTexture::clear and use it from paintredirector
also work around broken fbo texture clearing on fglrx

so far supports FBO/glClear and resorts to glTexSubImage2D

if the fbo cannot be created or is (in case of fglrx)
known to break, resort to glTexImage2D loading of an
argb array of zeros

Fredrik Höglund 2fc2004119 kwin: Reset the dirty flags in GLTexture

Martin Gräßlin aa549f45d5 OpenGLPaintRedirector updates textures directly
Ownership of decoration textures is moved from SceneOpenGL::Window to
OpenGLPaintRedirector. The PaintRedirector is responsible for updating
the textures whenever they change. For this GLTexture is extended by an
update(QImage, QPoint) method which uses glTexSubImage2D to update only
the changed parts.

The big advantage compared to before is that if e.g. only a button is
animated only the button part is updated instead of the complete deco
part.

Martin Gräßlin cf5de22586 Introduce a build option KWIN_BUILD_OPENGL_1_COMPOSITING
If the build option is enabled KWIN_HAVE_OPENGL_1 is passed as a compile
flag when build against OpenGL.

This compile flag is meant to replace the KWIN_HAVE_OPENGLES. So far code
has been ifdefed for special behavior of OpenGL ES 2.0 and to remove
fixed functionality calls which are not available in OpenGL ES 2.0.

With this build flag the fixed functionality calls which are only used in
the OpenGL1 Compositor can be removed and keeping the KWIN_HAVE_OPENGLES
for the real differences between OpenGL 2.x and OpenGL ES 2.0.

E.g. a call like glColor4f should be in an
glColor4f(1.0, 1.0, 1.0, 1.0);

while a call like glPolygonMode should be in an
glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);

Building for OpenGL ES 2.0 of course implies that KWIN_HAVE_OPENGL_1 is
not defined.

Philipp Knechtges 87bcabdf99 kwin: improving the texture update handling
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.

Martin Gräßlin fb2fbed035 Generate texture coordinates for limited NPOT support
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.
