3909f9b6e4 blit: lift 8x8 restriction from back2front 
This patch allows for the use of the back2front operation with textures
that are not a multiple of 8x8 pixels, which makes the utility
compatible with screen resolutions like 1366x768. In such cases, the
implementation falls back to the non-SIMD variant.

21acbed65b blit: Blit::blend_xrgb_a 
This commit adds support for SIMD-based alpha blending, which speeds up
the alpha-compositing of the nitpicker GUI server by circa 300% on ARM
Neon and x86_64 using SSE4.1
