From 39cf417e17011a72dd39acfe4cc8c90af26bdbaf Mon Sep 17 00:00:00 2001 From: Doug Zongker Date: Thu, 6 Mar 2014 16:16:05 -0800 Subject: remove pixelflinger from recovery Recovery now draws directly to the framebuffer by rolling its own graphics code, rather than depending on libpixelflinger. The recovery UI is modified slightly to eliminate operations that are slow with the software implementation: when the text display / menu is turned on, it now appears on a black background instead of a dimmed version of the recovery icon. There's probably substantial room for optimization of the graphics operations.
