Log Message:
Added drawing surface config "samples" attribute for multisampling.

The new keyword "samples" indicates the number of samples per pixel for
multisample visuals.  Non-multisample visuals report samples=0 (not 1).

Example: to run tests only on non-multisample visuals use the command
line option:  --visuals "samples==0"  Or, to run tests only on visuals with
four or more samples/pixel: --visuals "samples>=4"

Log Message:
In Windows makefiles, replace "deltree /y" with "rd /s /q"

deltree isn't in later versions of Windows.  rd should work on older versions
of Windows too.
