Description Susan McCourt

With CSS based layout, we need to use z-index to ensure that the banner/footer remain on top of content, that the splitter remains on top of content, etc.  I used rather large numbers (multiples of 100) to ensure this, and that broke some assumptions in the editor about what z-index will ensure that hovers appear on top of content.

Talked to Silenio.  We'd like to leave the content areas untouched for z-index and then use explicit z-index for the header, footer, splitter.  We would then want to make sure that hovers and dialogs (like key assist panel, global search, ocntent assist) have a known number that they can use to force "always on top" behavior.

We need to find a place to document these numbers so that other components know what the "always on top" number is.

fixed with http://git.eclipse.org/c/orion/org.eclipse.orion.client.git/commit/?id=1ad7cc89b7abd483bd393b878f661c382d981cc9

I restored the tooltip for z-index of 100.  I documented in both ide.css and layout.css that "100" is a value that ensures something will be on top of all of the other Orion components.
