Subject: [PATCH 213/398] editeng tiled rendering: avoid selections callbacks
 in Paint()

Given that we emit selection callbacks on each logical operations (set
selection, deselect all, etc) already, it's not necessary to emit
callbacks in DrawSelection() when it's called from Paint().

Change-Id: I6781c71ee2f292de2a1c7d129fc49b514aca2be1
(cherry picked from commit 11754fd7923c727e921bb6cbaf88d2765082667c)
