MapInfo Pro

There are different types of fill patterns. The first 2 in the style picker are None and Solid. Then there are 6 hatch patterns. All the rest are bitmap fill patterns. 

All the bitmaps used for region fill patterns are now into the MiAuxResources.dll file to make them easier for users to edit if they need to. All they need to do is load the DLL into a resource editor like Visual Studio and edit it.
