commit 5cc65a54a8c85daf3938acdf0adfe62c8b805693
Author: Christian Hergert <christian hergert me>

libide: add IdeSourceView:show-search-bubbles gproperty
This will render search bubbles around the search results during a
draw_layer (so they are appropriately pixel cached). This will default
to on in Builder, but off in the widget itself.
