-// This sample demonstrates the cache behavior of bitmap vs. distance field text
-// It renders variously sized text with an animated scale and rotation.
-// Specifically one should:
-// use 'D' to toggle between bitmap and distance field fonts
-// use '2' to toggle between scaling the image by 2x
-// -- this feature boosts the rendering out of the small point-size
-// SDF-text special case (which falls back to bitmap fonts for small points)
