  fix initial paint and fullscreen->region paint switch

  When we go from doing fullscreen paints to doing region paints there is no
  data in the framebuffer for EGL_post_sub_buffer to draw on so we get a black
  screen. This change makes us do a fullscreen paint but go through the region
  paint code path so further paints will have something to draw on. On desktop
  GL this change makes the first frame with the unityshell plugin draw correctly.

message:
  GL_BLEND : don't assume plugins are properly managing GL_BLEND states

  In fact, they don't. For example, the unityshell plugin uses a
  glEnable()... glDisable() kind of paradigm when dealing with *all*
  of the GL states (culling, stencil, blending, etc...). So assu-
  ming that blending is turned "on" by default is completely wrong
  when loading the unityshell plugin. This leads to all sorts of
  visual artefacts, window blackness, etc...

  To fix this, let's NOT assume that plugins take proper care of
  setting GL states back to there previous states when returning
  from functions.

  This fix sets appropriate GL blending before every call to
  vertexBuffer->render(...) in the openGL plugin.

  refactor painting the screen on GLES

  Removed fullPaint option from glPaintCompositedOutput as this hook is now
  only called on fullscreen redraws. Instead of rendering partial screen updates
  to an FBO we now use EGL_NV_post_sub_buffer. This should be faster and more
  closely matches how we have to render when using desktop GL. When this
  extention is not available we now do nothing but fullscreen redraws to avoid
  the rendering issues the FBO usage were intended to solve.

  Note: This has not yet been tested on actual hardware that has the extension
  or hardware that doesn't preserve buffers by default.

  Fix partial screen damage rendering to allow plugins to shade final composited screen.

  Partial screen damage rendering, driven in GLPrivateGLScreen::
  paintOutputs(), renders every GLwindows to an offscreen FBO
  (scratchFbo) and then renders damaged parts of this FBO to the back
  buffer. However, plugins needs a way to get access to scratchFbo
  if they want to be able to add screen-based FX on it while shading.

  This patch adds another GLScreen hookable called glPaintCompositedOutput.
  The 'bool fullRepaint' argument tells the function to whether or not
  perform a fullRepaint (useful in some situations, e.g. when
  COMPOSITE_SCREEN_DAMAGE_ALL_MASK is defined) or not (partial repaint).

  Plugins can benefit from hooking to glPaintCompositedOutput because
  they can then access scratchFbo (which should be renamed, really)
  before going to partial repaint. A plugin might then just decide to
  use scratchFbo's color_attachment in an FX shader and render that
  to the backbuffer, completely bypassing partial damage repaint.

  Add GLUniform per-plugin mechanism

  Currently, the openGL plugin binds the active program in GLWindow::
  glDrawTexture (). Since this is the last plugin-hookable function
  before hitting priv->vertexBuffer->render (), plugins are currently
  unable to set GL uniforms within their respective ::glDrawTexture
  callback because the main shaders are not yet compiled and bound.

  This patch adds "addUniform{...}" facilities to the GLVertexBuffer
  class. Since vertexBuffer is the only way for plugins to draw

  On GLES, render partial screen damage to FBO

  EGL or GLES 2 do not have a standard way to do partial back-to-front
  copies. Unfortunately compiz relies on blitting sub-rects from back
  buffer to front buffer for updating only the damaged regions. Compiz'
  rendering does not honour damage regions, but renders all over,
  sometimes leading to visual artifacts if one simply calls
  eglSwapBuffers().

  The fix: All output rendering is diverted into a framebuffer object
  (FBO), if the FBO is successfully created. Then, only the damage regions
  are blitted to the back buffer, followed by eglSwapBuffers().

  For full screen damage, the FBO step is skipped.

  This patch fixes rendering artifacts in the scale plugin, on GLES 2.

      Check OES_texture_npot mipmapping in GLES2

      GLES 2 spec does not support any mipmap filters for non-power-of-two
      textures. To my understanding, the support is added by
      GL_OES_texture_npot extension.

      Do not generate mipmap levels nor use mipmap filters, if it is not
      supported:

      - add GL::textureNonPowerOfTwoMipmap flag, which gets enabled only if
        OES_texture_npot is available (EGL / GLES 2), or equals
        GL::textureNonPowerOfTwo flag for desktop OpenGL.

      - check GLTexture::mipmap () instead of opencoding something similar in
        GLTexture::enable (). All these tests are moved to GLTexture::setData
        () callers, which are supposed to determine if mipmapping the texture
        is possible.

      - all cases, that set PrivateTexture::mipmapSupported via
        GLTexture::setData () now check for all the previous conditions plus
        GL::textureNonPowerOfTwoMipmap (except TfpTexture::bindPixmapToTexture
        () which does not need it).

      This patch fixes the window thumbnails in switcher plugin for GLES 2
      platforms that do not support mipmapping NPOT textures.
