[Chameleon] Locate layers

[Vicente Espinosa Garcia]

Thank you for your code is perfect for my project, but with this code I only 
get the layers used in a request and my main problem is to know How many Kbs 
a wms server send to wms client in a request. I only want to know the Kbs of 
map sent ( The map that a user see in the secreen). Is posible to get this 
information in Chameleon source code?. I wait that you understand my 
question. Thank you very much.
