Make drawing the grid configurable from xml/APIs #551

Closed RoboErikG closed 7 years ago

RoboErikG commented 7 years ago

VirtualWorkspaceView has a flag, mDrawGrid, which controls whether or not the background grid is drawn. This flag isn't currently exposed in any way, but should be configurable.

[x] Add an API for setting mDrawGrid.
[x] Add an xml attribute for configuring mDrawGrid in layout.
