HACK: force hardwareAccelerated to false on all apps.
This forces all apps to draw their Canvas with pure software Skia instead of HWUI. Result: an order of magnitude speedup on software rendering. Reason: HWUI uses GLES to render the Canvas. This works fine with hardware backed GLES. However, it is much slower than Skia when using a software renderer for GLES (e.g. llvmpipe or SwiftShader). Problem: breaks some apps like ScreenLock and Trebuchet. This dirty hack should be turned into a system property.
