Description
Tests the behavior when fog is enabled but the fog coordinate is not specified by the shader.
This test reproduces behavior observed in "Blade 2"

CarryoverLineLoop

Renders a series of primitives using various draw modes on the left, setting fog coordinates. Then renders a quad using the same draw mode on the right without specifying a fog coordinate at all. The fog mode is set to EXP.
