Android: OpenGL can only load 24- and 32-bits images.
Even with the 'depth' argument some png's becomes 8-bits images
(mogrify 6.7.7-10 2014-08-21 Q16), but at least the intro does not crash anymore.
Before the intro image 'joshcorp.png' became 8-bits.

Runs on Android 5, so raised the API level (min is still 2.3.3).
