Acquisitions (and other Dojo-based interfaces) generally don't respect global font settings

[Lebbeous Fogle-Weekley]

To quote Sharon Herbert of Sitka:

---

No part of the Acquisitions Module follows the global font settings. Some staff depend on the ability
to increase the font size in Evergreen.

I talked to Jason Etheridge about this in IRC. He believes he sees a straightforward approach to correcting this in Acquisitions and other similary-constructed interfaces that exhibit the same problem, and he has agreed to note his thoughts here.

Here's the bird's eye view of how the font settings work now in the XUL interfaces:

1) global.css file gets loaded by every interface

It contains lines like this:
.ALL_FONTS_SMALLER * { font-size-adjust: .3 !important;}
.ALL_FONTS_SMALLER *|* { font-size-adjust: .3 !important;}

which affect any elements and descendants with the corresponding classname.

2) during the onload event interfaces will call font_helper()

This looks at the desired font settings (stored with OpenILS/data.js) and sets classnames like ALL_FONTS_SMALLER on document.documentElement, triggering the CSS.

So, for non-XUL interfaces that get embedded in the staff client, we could either have them do something similar, or, if they're wrapped in a XUL <browser/> powered by util/browser.js, we could try to have browser.js do the work and inject CSS and CSS classnames into the embedded page with every page load. That might work.
