# Number of pixels below which 2D canvas is rendered in software

# 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

# This is a quirk we are pro-actively applying to old applications. It changes keyboard event dispatching,

# This is an iOS-specific quirk. Unlike Mac, keyboard operations are asynchronous and hence a DOM update as
# a result of text insertion or deletion does not occur within the same event loop iteration as a dispatched
# DOM keydown event. Some sites, notably Google Sheets, schedule timers on keypress and expect on a DOM update
# to have occurred on expiration. When enabled, this quirk puts all such scheduled timers in a holding tank
# until the keyboard performs the insertion or deletion. This gives Google Sheets the illusion that the DOM
# update happened within the same event loop iteration that the keypress event was dispatched in.
