Faithful recreation of RenderSpriteQuads (0x5A0F50) with hoisted invariant division and inlined DisplayMode_CalculateOffset. No measurable improvement — cost is dominated by getAdapterInfo (7 sub-calls to D3D device per invocation × 3203 calls/frame) and DrawPrimitive/DrawIndexedPrimitive virtual dispatch. Added decompilation and assembly dumps for future reference.
