Subject: [PATCH 213/398] editeng tiled rendering: avoid selections callbacks
|
|
|
f325b2 |
in Paint()
|

f325b2 |
Given that we emit selection callbacks on each logical operations (set
|
|
|
f325b2 |
selection, deselect all, etc) already, it's not necessary to emit
|
|
|
f325b2 |
callbacks in DrawSelection() when it's called from Paint().
