clutter/stage-view: Ignore clipping rectangle for offscreen blit
In clutter_stage_view_blit_offscreen()
, the given clipping rectangle
is in “view” coordinates whereas we intend to copy the whole actual
framebuffer, meaning that we cannot use the clipping rectangle.
Use the actual framebuffer size, starting at (0, 0) instead.
That fixes the issue with partial repainting with shadow framebuffer when fractional scaling is enabled.
