Description
Loading large images, especially JPEGs, is a common operation in FX apps.  It is also common for FX apps to create lots of small thumbnail images from large originals (e.g. in a photo viewer).  Investigation has uncovered lots of inefficiencies in the image loading/scaling process that need to be fixed.

This bug report will serve as an umbrella for more specific reports.
