Editing WoW:API Region GetBottom (section)

== Notes ==
As an object moves towards the top of the screen, the return values for GetTop/GetBottom increase. As an object moves toward the right, the return values for GetLeft/GetRight increase. This function works for all objects including UIParent and WorldFrame.

This function is only guaranteed to work after the PLAYER_LOGIN event and then, only if the object in question is being Shown.  Also, currently if you re-anchor an object or Show it, you will need to wait until after the next [[UIHANDLER OnUpdate|OnUpdate]] event before this function will return the correct new value.

The values returned by this function are generally not nice whole numbers but are often close. Example: 767.99994277954. Use <tt>floor(bottom + 0.5)</tt> to make integer.
