From 023fb41bb45d0dd049f1c2c97b9e3617b34fa892 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Tue, 31 Jul 2012 10:31:40 +0200 Subject: test_output: add blitting support When opengl rendering is not available on the target device, we now fall back to software rendering. Instead of drawing a nice gradient we now draw a white screen to the target device to avoid heavy calculations.
