ShadowDepthShader class final
shadow_depth.frag: window depth into a colour target.
A colour target rather than the depth buffer because flutter_gpu gives no
way to sample a depth texture, and the workaround is in the engine rather
than in any one backend. gl_FragCoord.z is the right value because the
shadow camera is orthographic — under perspective it would be hyperbolic,
all its precision near the near plane, and comparing two of them would mean
nothing.
