API GameTooltip SetFrameStack

Displays the frame stack of the mouse cursor's current position on the tooltip. This is not intended to be used in typical addons, but is part of the Blizzard_DebugTools "builtin addon" inspired by DevTools.

GameTooltip:SetFrameStack([showHidden, showRegion, highlightIndexChanged])

Arguments

 * showhidden : boolean - If true, includes in the display those frames which are currently hidden. Defaults to false.
 * showRegion : boolean - If true, includes frame regions. Defaults to false.
 * highlightIndexChanged : number - Which direction and by how much the index arrow should jump, e.g. -1, 1, 2, 3. Defaults to 0.

Example
Sets the GameTooltip to show mouseover frame stack information, includes hidden frames and frame regions and moves the index arrow downwards by 1. GameTooltip:SetFrameStack(true, true, 1)

Details
The frame listing on a tooltip after this function is called are arranged by frame strata and level. Within that list, the frames are colored:
 * Yellow/Orange : frame for which IsMouseEnabled is true
 * Blue/Teal : frame for which IsMouseEnabled is false
 * DarkGrey/LightGrey : frame that is hidden (when showhidden is true)

In each of those pairs, the colors alternate based on the frame level. For example, in a series of four frames all with the mouse enabled and within the same frame level the colors will alternate like this:
 * 4 Orange
 * 3 Yellow
 * 2 Orange
 * 1 Yellow
