When a css value has "child" css values (e.g. a linear gradient has several color stop css values) which are all computed (won't change when compute() is called on them), we want to skip computing the entire subtree. Since css values are immutable, we can set the is_computed flag at construct time. Since GtkCssValue instances are 0-initialized in _gtk_css_value_alloc, the default for is_computed it FALSE. This commit only sets it to TRUE in a few cases, such as various "none" singleton values which will never change. Later commits will refine this and set it for more values.
