+# Test that varying packing can properly pack floats, ints, and uints
+# together into the same varying slot.
+#
+# In order to force this to happen, we use a shader whose "varyings"
+# are a float, a uint, and an array of gl_MaxVaryingComponents-2 ints.
+# All "varyings" use the "flat" interpolation type, since we don't
+# intend to test the packing of interpolation types in this test.
