BUG: 385097
This revision further improves the quality of images in notifications that was addressed in revision D9993. When I first looked into this, I tried setting ScaleType on the PreviewJob but it had no effect. I found that the preview images were being scaled to the small vertical size that was requested, and this resulted in my first revision. I should have tried setting ScaleType in addition.
Notification with unpatched libnotificationshelperplugin.so
