I have created two markers on a map, one a standard marker, the other using an SVG path. The standard marker does not move relative to the map when I zoom out, but the SVG marker does. Here is a fiddle where you can see what I mean:
Any thoughts on how to get the SVG marker to hold its place relative to the map?

You must define the anchor for the symbol(for a symbol the default is the top left corner, while default for a image is the bottom center)
For this specific symbol the Point for a bottom center anchor would be approximately
258,381Demo: http://jsfiddle.net/a3LKP/5/
Explanation of the calculation of the origin at bottom center(for inkscape).
Let's assume you didn't create the path(symbol) on your own, create a SVG-document with the given path:
Open this document with inkscape.
First go to
File->document-properties->pageto determine the document-height(for me it's 1052.36px , I guess that's the default)Then click on the symbol to select it, in the menubar you should see the properties of the object: X , Y , W(idth), (H)eight.
For me it's now:
document-height: 1052.36
object-x: 130.909
object-y: 671.362
object-width: 254.155
object-height: 286.093
calculating the y of the bottom :
substract the object-y from the document-height(1052-671=381)
calculating the x of the center :
add the half of the objects width to the objects x(131+(254/2)=258)
So the anchor is
new google.maps.Point(258,381)
