; Name ..........: MDMF - Multiple Display Monitor Functions
; Description ...: Various functions for multiple display monitor environments
; Tested with ...: AHK 1.1.32.00 (A32/U32/U64) and 2.0-a108-a2fa0498 (U32/U64)
; Original Author: just me (https://www.autohotkey.com/boards/viewtopic.php?f=6&t=4606)
; Mod Authors ...: iPhilip, guest3456
; Changes .......: Modified to work with v2.0-a108 and changed 'Count' key to 'TotalCount' to avoid conflicts
; ................ Modified MDMF_Enum() so that it works under both AHK v1 and v2.
; ................ Modified MDMF_EnumProc() to provide Count and Primary keys to the Monitors array.
; ................ Modified MDMF_FromHWND() to allow flag values that determine the function's return value if the
; ................    window does not intersect any display monitor.
; ................ Modified MDMF_FromPoint() to allow the cursor position to be returned ByRef if not specified and
; ................    allow flag values that determine the function's return value if the point is not contained within
; ................    any display monitor.
; ................ Modified MDMF_FromRect() to allow flag values that determine the function's return value if the
; ................    rectangle does not intersect any display monitor.
;................. Modified MDMF_GetInfo() with minor changes.
