basically it's the same technique we've been using for Krita -- it's really 
not inefficient, since you first load and parse a small xml file (and even 
with hundreds of layers and masks, it'll still be really small xml file 
compared to the average tomcat web app configuration file), and then you just 
load the binary pixel data for each layer. In openraster, that's in png 
format, in krita it's uncompressed bytes -- but given that both are in a zip 
file, that's not a big difference.
