add temporary cast to allow Skia roll

    const float* vArray = (const float*)vertices->positions();

    const float* tArray = (const float*)vertices->texCoords();

    const int* cArray = (const int*)vertices->colors();

    mCanvas->drawVertices(vertices->mode(), floatCount, vArray, tArray, cArray,

    // Can remove this cast after changing to SkVertices::VertexMode

    SkCanvas::VertexMode vmode = static_cast<SkCanvas::VertexMode>(vertices->mode());

    mCanvas->drawVertices(vmode, floatCount, vArray, tArray, cArray,

            vertices->indices(), vertices->indexCount(), paint);
