[OpenLayers-Dev] bad misaligning of KML point layers?

[Lance Dyas]

For google earth scale feels like the dominant element of how it 
renders... whatever the images
pixel x pixel dimension.. 

The KML parsing code built in to the API's GGeoXml is server side at google
so I am uncertain what magic it does I do know it isnt always perfect 
and doesnt
even always find the marker styles correctly.

And creating custom Markers are very persnickety in the Google Maps API
as an image map to indicate the clickable parts has to be created 
explicitly for
most browsers but IE uses the images transparency.

There was even a fairly recent error where the default icon became 
unclickable
in IE6 for what seemed like nearly a week

The extensions to the google api where people make there own kml parsers
have a basic over-ride where they can define a default icon of there own
and which the the hotspots etc are all defined by.

Not certain what is wise ... there are tricks... pre-load an image and 
it will give
you its dimensions perhaps this could be leveraged

var aimg = new Image();
aimg.src = "http://maps.google.com/mapfiles/kml/paddle/purple-stars.png";
aimg.onload= function () { alert(aimg.height); }
