kde: Explicitly use the global namespace to refer to the X11 Region type

The introduction of KDecorationDefines::Region in recent KDE libs mandates
that we are explicit about which Region type we are referring to.

use FBO for partial screen paints again

Always bind the FBO for drawing and call glPaintTransformedOutput every frame.
Readded the mask to that call so plugins know if it was a partial redraw or not.
Also added API for plugins to get the FBO at any point, this is needed for unity
so it can update its blur area.

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.
Thanks for Frederic Plourde for almost all of this change.

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.
