pixman-renderer: move code to draw_view_translated()

Move code from draw_view() into a new function draw_view_translated().
This new function is correct only if
view_transformation_is_translation().

The test for view->alpha is moved into draw_view_translated() too, so we
don't need to pass the pixman_op from draw_view(). The non-translation
path is already using PIXMAN_OP_OVER, so it does not care about the
alpha.

v2: Fixed commit message.
