wx.Region no longer selects all non transparent pixels when a wxBitmap is passed to the constructor. In order to get the region made properly a color bust also be supplied. As luck would have it the way the docking guide images were made we are able to do this because there is only a single color that we needed to use.
wx.lib.agw.aui was never converted to run on Python 3 and as a result the division operator forces a conversion of the used values to a float. Floats cannot be used in functions like `range`. This caused quite number of things to not function properly and produce tracebacks.
The other thing is when wx.lib.agw.aui was written pixels could not be rendered using coordinates that were floats so now passing floats could cause rendering alignment problems because the layout of the various bits were done so in a manner that would have the alignment correct using integers.

When I added this code in 5e190eb, it was intended to be used in all cases
except for constructors and destructors. Instead, it was used in all cases.
This broke the wxRegion constructor and possibly other things.
Fixes#1878.
