[Design] [Cosmo] Supported browsers for Cosmo

[Priscilla Chung]

A while back the UI team for Cosmo settled on a proposal of browsers  
to support. There are two issues which this list of will help us with:

+ Prioritize on bugs, especially before a release.
+ Help us focus on the the 'ideal design' in the UI elements, ie.  
spacing, alignment etc.

The list of browser support in priority are:

    1. Windows Firefox
    2. Windows IE7
    3. Windows IE6
    4. Apple Firefox
    5. Safari
    6. Linux Firefox (note: Matthew is currently developing in this  
so the app will work fine in Linux)

Target screen size - 1024x768 pixels.

I think we're all in agreement that the target size we should focus  
on for a web application is 1024x768 pixels–min screen resolution.  
Though the web app should still be usable at 800x600 pixels though it  
does not need to 'look good'. So for example, the calendar canvas  
will look squished, but is functional to double click on the calendar  
canvas to have an event lozenge appear.

If there are no other objections to this proposal, this will be  
documented for Preview and made clear in the test plans for QA.
