fix png images with pixel ratios <0.5 crashing the app (#2350) 
When we handle pixel ratios in .png files, we were rounding the pixel
ratio to the nearest integer. This mean that if an image had a pixel
ration less than 0.5, it would get rounded to zero. This would cause a
divide-by-zero on the width & height of the image which would crash the
app.

This has a couple fixes:
- we ignore pixel ratios less that 1
- we perform rounding _after_ we apply the pixel ratio to the
width/height

### Change Type
