Partway through adding map window coordinate calculation support, not done yet.
Corrected calculations.  This correctly calculates the top-left coordinate now.  Still missing is the tile width, but that's easy.
Added calculation of map tile size.
Forgot to update the tile size when the aspect ratios perfectly match.  The code to calculate where the map should be in the window at all resolutions looks done.
Merge remote-tracking branch 'origin/master' into map_window_data

Added some comments as well as a windowToMap function to perform the inverse of mapToWindow.  Both of those functions are stubbed out out the moment.
Clarifying comment.
Filled out map to window conversion functions and made them return whether or not the conversion was successful.  Updated comments.
Corrected out-of-bounds checking in windowToMap.
