I tried to create Graphics primitives using the techniques in this, found problems with parallel rasterization

SetAttributes[createPrimitive,HoldAll];

createPrimitive[patt_,expr_]:=Typeset`MakeBoxes[p:patt,fmt_,Graphics]:=Typeset`MakeBoxes[Interpretation[expr,p],fmt,Graphics];

createPrimitive[face[x_:0.1],{Circle[{0,0},1],Circle[{-0.3,0.5},x],Circle[{0.3,0.5},x],Line[{{-0.4,-0.2},{0.4,-0.2}}]}];

ParallelTable[Graphics[{face[i]},ImageSize->Tiny],{i,0,0.3,0.3/5}]
ParallelTable[Rasterize@Graphics[{face[i]},ImageSize->Tiny],{i,0,0.3,0.3/5}]

Is there any way to fix this?
