GPU_DEPTH_NONE leads to issues with Intel GPU drivers on Windows
where camera gizmos cannot be shifted. glGetQueryObjectuiv for
GL_SAMPLES_PASSED seems to return zero in all cases.
This might be due to undefined behavior of OpenGL when the depth
test is disabled and rendering to a depth render target-only
framebuffer. Using GPU_DEPTH_ALWAYS fixes the issue.
