[Lazarus] SVG Object

I'm afraid there is no easy solution for that. SVGs are rendered from 
the first element to the last, where ever element (atleast in theory) 
can be a part of a given pixel. SVG elements do have a x,y,width,height 
but they may also be part of one or more transformations.
To give you an idea, the (browser)app I'm currently working on displays 
several object, where every object has an origin(x,y) of 0,0 and they 
are finally placed by translations.
The easiest way (if you are in a browser context) is to add an onclick 
handler to your elements of interest.
