Improve rendering speed by disabling scissor tests

This change improves execution of display lists, particularly on
tiled renderers. The goal is to disable the scissor test as
often as possible. Drawing commands are rarely clipped by View
bounds so most of them can be drawn without doing a scissor test.

The speed improvements scale with the number of views and drawing
commands.
