commit 6a0aa2cf499bbd2a8a6d957732f2be47bfdcb750
Author: Fabian Lange <lange.fabian at gmail.com>

    Set transformOrigin for text layer in css.
    
    transformOrigin is set to 0% 0% in all cases. This adds extra memory
    impact into the dom tree. It also involves the CustomStyles workaround
    to determine the correct css rule for the browser.
    By setting all vendor and standard variants in css, the rule is applied
    without the dom memory overhead and without the minor computation
    overhead to set the value.
