Clamp ReadPixels calls to unsigned limits in D3D11. GL allows reads beyond the defined pixel rectangle, although their resultant values are undefined. D3D11 gives an error when reading out-of-bounds, hence clamping the area satisfies both APIs. This fixes a Renderer crash in our ReadPixels out of bounds test, and also fixes the test to test the correct area of pixels.
