texture: Remove reading the texture data back in ::unrealize() ...
Reading back the texture data in unrealize does not seem like a
desirable feature any more, clutter has evolved a lot since it was
implemented.
What's wrong with it now:
* It takes *a lot* of time to read the data back with glReadPixel(),
* When several textures share the same CoglTexture, the same data can
be read back multiple times,
* If the underlying material uses multiple texture units, only the
first one was copied back,
* In ClutterCairoTexture, we end up having two separate copies of the
data,
* GL actually manages texture memory accross system/video memory
for us!
For all the reasons above, let's get rid of the glReadPixel() in
Texture::unrealize()
Fixes: OHB#1842
