This implements the Caps throttler. After some testing, the system seemed to be OK with me specifying allowing 1 oversized image per 70,000b/sec with at least one. Try it out, start with a low bandwidth setting and then, set your bandwidth setting middle/high and see the difference.
Tested with Two Clients on a region with 1800 textures all visible at once.
