In 4.4 alphaMapForGlyph() would return valid images for any font size,
but this was changed in 4.5, forcing us to use the path fallback
instead. This lead to non-antialiased fonts when not using a
multisample-enabled GL format. This patch re-introduces the
alphaMapForGlyph() fallback in QFontEngine from 4.4 which uses the
raster paint engine to draw the glyph.

QGLWidget does not support partial updates unless the context is
single buffered and auto-fill background is disabled. The problem
was that QPaintEvent::region() returned the requested update region
without taking into account the limitation of QGLWidget. If QGLWidget
doesn't support partial updates, it means everything has to be updated,
and QPaintEvent::region() must return the whole widget rect.
Auto test included.

Use painter paths instead of rectangles for perspective transformed
rects, as the rectangles might have been clipped.

The NSOpenGLContext seems to be tied to the window. So if the view
changes from one window to another, the OpenGL context needs to be
cleared. We can do this by hooking into the viewWillChangeWindow and
viewDidChangeWindow events and clear and reset the drawable
respectively. We also found out that QCocoaOpenGLView was not being used
at all, so just remove it to get rid of any confusion.

QGLPixelBuffer::generateDynamicTexture() will bind the texture to the
pbuffer regardless. Why this works on Carbon is a mystery, but if we're
to follow our own docs, we should NOT bind the texture to the pbuffer
by default. An explicit call to ::bindToDynamicTexture() is required for
that.

with Cocoa support on Mac.
The Cocoa API doesn't have a concept of Z-ordering of widgets, and it's
implemented by reordering the widget hierarchy for normal widgets. This
does unfortunately not work for GL widgets, and it's not supported by
Apple. This apparently work with the Carbon AGL API though.
