screencasting: generate the composed textures with the proper size

Browse source 
Don't neglect the scale of the buffer for windows that we are rendering
on the spot.
Otherwise we will be offering a smaller size to what we are generally
using. More importantly, the ScreencastManager expects the buffers
scaled. This causes glitches when the stream starts otherwise as the
first frame triggers a resize.
