Add a checkered background to transparent artboards and the infinite canvas (#4022)

Browse Source 
* Add checkered transparency rendering to infinite canvas and artboards

* Enable artboard clipping by default

* Make new infinite canvas documents begin with a white background layer

* Remove the export dialog's transparency option now that it's redundant

* Make exporting transparent JPGs use white not black

* Code review
