Hello,  
Happy to have a new version 🙂

Trying new version, I get some issues:

gdk3 sample :

C:\Ruby22\lib\ruby\gems\2.2.0\gems\gdk\_pixbuf2-3.1.0-x86-mingw32\sample\>ruby  
composite.rb  
C:/Ruby22/lib/ruby/2.2.0/rubygems/specification.rb:2112:in  
`raise_if_conflicts': Unable to activate gobject-introspection-3.1.0-x86-mingw32, because glib2-3.0.9-x86-mingw32 conflicts with glib2 (= 3.1.0) (Gem::ConflictError) from C:/Ruby22/lib/ruby/2.2.0/rubygems/specification.rb:1280:in`activate’  
from C:/Ruby22/lib/ruby/2.2.0/rubygems.rb:198:in `rescue in  
try\_activate’  
…

with  
C:\Ruby22\lib\ruby\gems\2.2.0\gems\>ll -ld go\*

Then trying gtk3 demos :

main.rb

installing cairo manually (gem install cairo) seem has resolve issues  
by installing cairo-1.15.3-x86-mingw32

Then, after a second ‘gem install gtk3’, all works …
