+
+# Short description: Fragment shader that uses 'transpose'
+
+# The test passes because 'f' is invoked with a vector whose components are less than or equal to 1.0, so that it returns vec3(1.0, 0.0, 0.0), meaning that the output colour red is written
+
+# Optimized using spirv-opt with the following arguments:
