e-paper or simplistic greyscale LCD devices which have no color, such

in abilities (no support for smooth scale or transformations/map). in
a state of disrepair. do not use unless your hardware is just 16bpp
and very limited in CPU and memory.

// THEN allocated again - thus brignhjing ref to 0 then back to 1 immediately
// where it should stay at 1. - see evas_engine.c in the buffer enigne for
// example. eng_output_free() is called BEFORE _output_setup(). although this
// is only a SIGNE of the problem. we can patch this up with either freeing
// after the setup (so we just pt a ref of 2 then back to 1), or just
// evas_common_image_init() at the start and evas_common_image_shutdown()
