# A test for a bug found by GraphicsFuzz.

|
# 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:

# layout(location = 0) out vec4 _GLF_color;
