shell-recorder: Use clutter-computed sizes and scaling for the capture

Browse Source 
Get from clutter the capture sizes and scale and don't mind
about doing any rounding here, as it might be different
from the one done at clutter level (causing mismatch and
not-working videos). Delegate this to clutter, and forget
about the internal details.

These values are then used to composte the image and set the video caps.
