Frame Strata

Frame strata (sometimes called frameStrata) orders each on the screen, affecting how they overlap. These strata divide the z-axis into nine intervals (from back to front):
# WORLD (see details)
# BACKGROUND
# LOW
# MEDIUM
# HIGH
# DIALOG
# FULLSCREEN
# FULLSCREEN_DIALOG
# TOOLTIP
Frame levels further divide each strata into smaller intervals, numbered 0-10000. Higher numbers appear above lower ones, but only if they share the same strata.
== Details ==
* WORLD is reserved for the world frame and cannot be assigned.
* Frames further partition the z axis into Layers when drawing a (e.g. Texture or FontString).
* Every frame defaults to appearing slightly above its parent, sharing the same strata but having one level higher.
* Set a frame's strata using:
**

* Set a frame's level using:
** to choose any value
** or to increase frameLevel to one higher than existing frames which were previously in front but within the same frameStrata
** for the opposite (no equivalent in XML)
** to make frameLevel the same as the parent frame (instead of normally being one higher)
