In general PIE is quite good at detecting changes to the size and position of the elements to which it
+is attached and automatically adjusting its rendering to match. It does this by listening to the IE-specific
+onmove
and onresize
events for each target element. In the majority of cases this
+works seamlessly; in rare cases, however, IE does not fire these events when it should, and PIE gets out of sync.
To help users get around these cases, PIE has a second method for tracking size and position changes: polling. +When polling is enabled for an element, PIE will manually query that element's layout several times a second, and +if the layout has changed then it will adjust the rendering.
+ +Polling is enabled by default for all elements in IE8 (as that version is particularly bad about not firing
+the events) and disabled in IE 6 and 7. Users can override these defaults
+to force polling on or off for individual elements by setting a custom CSS property: just specify
+-pie-poll:true;
to force polling on for an element, or -pie-poll:false;
to disable it.
