# Number of pixels below which 2D canvas is rendered in software
# even if hardware acceleration is enabled.
# Hardware acceleration is useful for large canvases where it can avoid the
# pixel bandwidth between the CPU and GPU. But GPU acceleration comes at
# a price - extra back-buffer and texture copy. Small canvases are also
# widely used for stylized fonts. Anti-aliasing text in hardware at that
# scale is generally slower. So below a certain size it is better to
# draw canvas in software.
