# A test for a bug found by GraphicsFuzz.
# A fragment shader that uses pow.
# Derived from the following GLSL fragment shader.
# We check that all pixels are red. The test passes because main does
# some computation and then writes red to _GLF_color.
# #version 310 es
#
# precision highp float;
# precision highp int;
#
# layout(location = 0) out vec4 _GLF_color;
#
# void main()
# {
# vec2 a = vec2(1.0);
# vec4 b = vec4(1.0);
# pow(vec4(a, vec2(1.0)), b);
# _GLF_color = vec4(1.0, 0.0, 0.0, 1.0);
