** Test program for mouse drivers.

** 2001-09-13, Ullrich von Bassewitz
** 2013-09-05, Greg King
**
** Compile with "-DSTATIC_MOUSE" to statically link all available drivers.
** Compile with "-DMOUSE_DRIVER=<driver_sym>" to statically link the given driver.
**     E.g., -DMOUSE_DRIVER=atrst_mou to just link with the Atari ST mouse driver.
