// ========== Internet Explorer Notes ==========
// Looks like 3D Transform is only supported in IE 10 Developer Preview.
// Not in Platform Preview. Developer Preview is available only with Windows 8.
// Still 3D Transforms scale image in a peculiar manner such that images
// appear watered down and wobble when scaling over multiple map levels

// ========== Chrome Bug ==========
// Technically Chrome supports 3D Transforms since version 12, but has the 
// following problem identified in v15:
// Overall there are 3 unique issues:
// 1) Navigating from one feature to the next in the popup does not set proper 
//    scrollbar height - unless you pan the map while the popup is open with 
//    scrollbar leaking out. This issue is fixed by the txSuffix workaround
//    described below in esri._css scope.
// 2) On Windows, the scrollbar is invisible or very transparent so that users
//    dont see them, But can be clicked or dragged
// 3) Dragging the scrollbar or using mouse wheel does not scroll the popup
//    content
// Chrome at version 17 seems to have fixed issues #2 and #3 above.
// Note: 15.0.874.121 m is the stable version at the time of this writing, and
// 17.0.942.0 dev-m is the dev version.
// Note: 15.0.874.121 m with 2D transform flickers when opening a new tab
// and begin to zoom in.

// ========== Android Bug ==========
// Catch the case where Android Browser identifies itself as Safari as well
// i.e. both isSafari and isAndroid will be true.
// Android 2.x bug: http://code.google.com/p/android/issues/detail?id=12451
