Setting the PIGLIT_DEFAULT_SIZE to WIDTHxHEIGHT will change the
default from 160x160 to the requested value.
This can be useful if you want to make the number of fragments really
small. For example, PIGLIT_DEFAULT_SIZE=4x4 would only have 16 pixels
compared to the standard 160 * 160, or 25600.
Not all piglit tests will operate properly at every size, so this
environment variable should be used carefully.
