Chrome extension to improve position:fixed elements with transform:translateZ(0) for smooth 60fps scrolling.

Find the extension in google store here: https://chrome.google.com/webstore/detail/fix-fixed/dgemgghfpehbgjofnpdeidajmobbkhfg

Also i have fixed chromium.app itself to optimized position:fixed directly: https://dl.dropboxusercontent.com/u/96620836/Chromium.app.zip (Compiled for Mac latest version from git Feb 2015) I try to commit the changes to official chromium in several weeks when i understand the deploy process.

It works as follows:

• Chrome has bad rendering performance with style=position:fixed elements.

• This patch will load all the stylesheets (and even fetch them via XHR if they are blocked due to https)

• It is checking all cssRules if they are style.position == "fixed" and creates new css-code

• At the same time style.tranform != '' are collected, because they can lead to errors

• the new css are appended and the layers are optimized in future , as the stylesheet is now optimized.

• to avoid render-errors all real cssRules with transform in it are appended again and they cancel out the translateZ(0) if neccessary.

• All is done in one parse run, dom is not touched but only css-stylesheet is optimized in a way how the designer of the webpage should have done from the start.

• if classes are added or removed during scroll (eg. menu shows on scrollback) then all is fine.
