By default, glow uses a bicubic scaling filter on desktop platforms and a
bilinear scaling filter on mobile platforms. The bicubic scaling filter results
in higher quality with a less blocky appearance, but it has a performance cost
on the GPU which can be significant on integrated graphics.
The scale mode can be controlled using the
