[GEM-dev] negative gemhead order

[cyrille henry]

hello,

the gemhead doc says that :

Lower values (-10) will be rendered before higher values (-3). 
 ...
example: "1" before "50" before "-23" before "-10"

in fact, i think this is not true : 
real rendering order is 
"1" before "50" before "-10" before "-50"
