By the way, if I change the transparent map tile in the "Two Records" example to non-transparent the MapSource list still shows two records. Thus, I will get two records even if all map tiles are non-transparent in this case.

To change the transparency for this test, do as below.
Open the "Two Records" example by a hex editor such as UltraEdit or WinHex
Go to file offset 00025d27 in hex
Change the byte value there from 07 to 05
