/**
 * @class LLFloaterQuickPrefs
 *
 * A lightweight "Quick Preferences" panel that lets the user adjust commonly
 * tweaked settings on the fly without opening the full Preferences dialog:
 *   - Avatar hover height
 *   - Maximum network bandwidth
 *
 * Hover-height logic is ported 1:1 from Firestorm's FloaterQuickPrefs so that
 * live-preview while dragging, final commit on mouse-up, and region-feature
 * gating all work exactly the same way.
