GetMaximumVertexOutputVectors() will return 14 on 10.0 hardware vs 30 on 10.1 because of the difference in D3D10_VS_OUTPUT_REGISTER_COUNT (16) vs D3D10_1_VS_OUTPUT_REGISTER_COUNT (32)

It looks like we might be able to check this at build time using sh::CheckVariablesWithinPackingLimits

On 10.0 level hardware we only have 14 vecs of varyings allowed.
Reusing v_color_offset for v_flood_color gets us under the limit.
