content: Improve thread priority for raster threads.
This reduces the amount of resources that background work
can use by making the background thread that runs pre-paint
tasks use a priority that makes it run on a single small core
on big.LITTLE devices.
Threads used for foreground work are now given normal priority
on all platforms.
