7cc7f80ee2 Add dom depth information to render queue 2013-10-27 22:08:12 +02:00
ssafejava
8bea01b81d Speed & accuracy improvements to pseudo element rendering. 
Previously, pseudo elements would be processed as they were found in the DOM tree, which was
an expensive operation as each element's computed :before and :after style was checked for
'content' styles.

This commit traverses the user's stylesheets for :before and :after selectors, gathers the classes
affected, selects all elements that likely have a pseudo element present, then checks computed style.
If there is actually an element present, it is created but *not* appended to the DOM until after
all elements have been processed.

After all elements have been found and created, they are added to the DOM in a single batch, and the original
pseudo elements are hidden in a single batch. This prevents the layout invalidation / relayout loop that was
occuring previously, and in my tests speeds parsing by as much as 50% or more, depending on how many
pseudo elements your page uses.

Additionally, this commit contains a bugfix to the handling of ":before" pseudo elements; the browser effectively
inserts them as the first child of the element, not before the element. This fixes a few rendering inconsistencies
and complicated pages look almost perfect in my tests.

e115180731 Add async parsing option. 
In my testing, the major time sink is parsing. This commit adds a setTimeout() around parsing
of each item so control can return to the browser. This increases the total time it takes to finish
a screenshot but will not freeze the browser when it does. This is a good option when e.g. doing
error reporting, where you might not want to freeze the browser while sending debugging information
back to your server.

16d3bef255 z-index overhaul. relative above static; negative z-index 
1. when stacking without z-index, positioned > floated > normal flow
2. supports negative z-index
3. new stacking context formed when opacity < 1 (standard)
4. new stacking context formed for position:fixed (no standard yet, done in mobile webkit and chrome 22+)
