entry: Simplify selection rendering

Browse Source 
Calling gtk_render_background for each rectangle in the region
leads to suboptimal and sometimes weird results. Getting this
right requires more work in Pango first. Go back to just rendering
a single background, and clip it to the selection region. This
matches what GtkLabel does.
