Fix textdrawing under GL on N900.
The driver in the N900 doesn't support glCopyTexSubImage
or glReadPixels for FBO's that have a GL_ALPHA or POT
color attachment. The ifdef'ed code in resize() was
a previous attempt to make this work which didn't.
We could have changed the texture to be GL_RGBA and changed
the texture size to be NPOT, but that would have wasted
precious GPU memory and would have been slower, so we
waste a bit of system memory instead, by having a QImage
copy along with the texture.
