From 1a820e90d8848c6b0ac7c78b5a2e8b28c9738a3a Mon Sep 17 00:00:00 2001 From: Vladimir Chtchetkine Date: Wed, 11 Apr 2012 13:22:48 -0700 Subject: Enable multi-touch emulation with -gpu on This CL implements a callback that gets invoked by OpenGLES emulator on it framebuffer updates. This allows transferring framebuffer changes to the supporting device. Proper implementation of this new callback also required changes to JPEG compression, addressing: 1. OpenGLES framebuffer format is RGBA8889, which required implementing line conversion for this format. 2. OpenGLES framebuffer is (or at least could be) bottom-up arranged. This requires changes to the compressor, so it compresses the FB starting from the bottom, so the resulting image is up-bottom.
