BHV-15685: Panels branding was causing unnecessary full-screen-repaints during every panel transition. This caused lag and blinking, as well as other performance issues.
* Branding is now set once, instead of every panel transition.
* Branding now has an appropriate size imposed on it. (Instead of none whatsoever)
* Breadcrumb height is now a variable.

Run a lower cost function to do the same thing.

Initializing Panels at an index greater than 0 results in the branding working as expected.
