Fire wp_auth_check_load() from admin_enqueue_scripts instead of admin_init so that it can access the current screen object.

Black list the update and upgrade screens.

Allow plugins to white/black list screens via the wp_auth_check_load filter.

Remove the Spellchecker button from TinyMCE.

It appears Google has finally shut off the old private API it used. Spellcheckers built-in to browsers (and operating systems) seem to be the best alternative.

A WordPress plugin could still re-enable this TinyMCE plugin if they wanted.

Revisions: Re-work how tick marks and tooltips are aligned. IE fixes.

* Pixel-based alignment of tooltips.
* Bottom-based alignment, so arrow lines up using CSS only.
* Better RTL styles (mostly mirror-imaged).
* Better RTL calculations in `revisions.js` (less logic).
* Better IE support.

WORLD WAR Z-INDEX: Restoration of sanity to revisions/slider/menu z-index values.

The year is 2013. It is a period of DOM unrest. Sliders have hoarded
all available z-index, leading to an arms race. What started as a local
squabble soon escalated into a global conflict. The flyout menus were
the first of the collateral damage, trodden underfoot by mighty warring
enemies they couldn't effectively challenge. It was said they were
betrayed by one of their own: the z-index-power-hungry non-active
currently-hovered submenu, whose z-index-power level was over 9000!

But there is hope. A small band of heroes has emerged. Using their
powers of "what were you thinking?" and "chill, no one needs a z-index
THAT high", they have begun to restore order and harmony to the DOM.

See #24736. Props markjaquith, aaroncampbell, helen.
