// When drawing on a 1x backing store it'd draw m_bitmap_1x at its physical size, and it would have to scale down m_bitmap_2x to 0.5x its size.
// But the system can't current scale down, and we want to draw the 2x bitmap at twice the size of the 1x bitmap in this particular application,
// so make a 1x alias of the 2x bitmap to make LibGfx paint it without any scaling at paint time, mapping once pixel to one pixel.
