zoom-out on image causes crash

[yyportne]

Zoom-out on image causes crash in riot version 0.8.20 (G-b159).

Steps to reproduce:
[1] Open image (image is displayed to fit in the display boundaries)
[2] Try to zoom out
[3] Repeat [2] until crash

I've noticed that in step [2] the image is sometimes displayed a few pixels smaller than the device boundaries before the crash occurs.
