# Division by zero test. Specification states:

# "Some calculations require division. In such cases (including implied divisions performed by
# vector normalization), division by zero produces an unspecified result but must not lead to
# Vulkan interruption or termination."
#
# This test performs various divisions (both implicit and explicit) and succeeds if it doesn't crash.
