# Defines properties which are available on the Settings object.
|
|
#
|
|
# Please think carefully before adding a new Setting. Some questions to
|
|
# consider are:
|
|
# - Should this be a RuntimeEnabledFeature instead? Settings are for things
|
|
# which we support either values of at runtime. Features are set at renderer
|
|
# process startup and are never changed. Features also tend to be set to a
|
|
# value based on the platform or the stability of the code in question, where
|
|
# as settings both codepaths need to be stable.
|
|
# - How will you ensure test coverage of all relevant values of your setting?
|
|
# - Is the default value appropriate for other platforms or ports which may
|
|
# not be aware of your setting?
|
|
# - Can your setting result in behavior differences observable to web
|
|
# developers?
|
|
# - Should this setting ideally be removed in the future? If so please file
|
|
# a bug and reference it in the comments for your setting.
|
|
#
|
|
# One reason to add a Setting is to manage the risk associated with adding a
|
|
# new feature. For example, we may choose to ship a new UI behavior or
|
|
# performance optimization to ChromeOS users first (in order to gather feedback
|
|
# and metrics on its use from the wild) before attempting to ship it to
|
|
# Windows.

#
|
|
# FIXME: Add support for global settings.
|
|
# FIXME: Add support for custom getters/setters.

# 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.
