On low-end devices, the current 48 fps boot animation can use more than 50% of CPU time, and if the texture cache is enabled, a majority of main memory as well. For these devices, add half-resolution variants of the lower-resolution boot animations which display 2x upscaled -- this greatly speeds the boot process and makes the boot animation run more smoothly.
