dix: Allow zero-height PutImage requests (fix for X.Org's CVE-2015-3418)
The length checking code validates PutImage height and byte width by
making sure that byte-width >= INT32_MAX / height. If height is zero,
this generates a divide by zero exception. Allow zero height requests
explicitly, bypassing the INT32_MAX check.
v2: backports to VcXsrv 1.15.2.x (Mike DePaulo)
