Erik fb288ad852 fix(D.5.2): effect tint = per-pixel tile copy (surface ReplaceColor overload)
Visual verification (Coldeve, Energy Crystal) showed acdream's Magical blue as a
flat tint vs retail's gradient. Root cause: RenderIcons calls the SURFACE overload
of SurfaceWindow::ReplaceColor (0x004415b0), which copies the textured effect tile
pixel-by-pixel into the icon's pure-white pixels — not the flat color->color overload
(0x00441530) I'd approximated with the tile's mean color. Port the surface overload
exactly (dst[x,y]=src[x,y] where dst==white); confirmed via clean Ghidra decompile +
named decomp. Retires AP-43 (mean-color approximation); IA-18 updated to the surface op.
