DisplayList draw operation reordering
bug:8037003
The reordering enables similar operations to draw together, minimizing the
OpenGL state change operations that go inbetween draws. Eventually, multiple
complete canvas draw operations will be merged (into a single glDrawArrays call,
for example)
Reorders DisplayList draw operations when:
-They can move backwards in the command stream to be after similar
operations without violating draw ordering
-The OpenGLRenderer is in a simple, replayable state (no complex clip,
or filter/shadow etc)
Also adds two system properties to control the deferral/reordering:
"debug.hwui.disable_draw_defer"
"debug.hwui.disable_draw_reorder"
which can be set to "true" to control the display list manipulation
