[ruby-fltk-devel] Fl_Group::begin() and end()

[Takaaki T. <tt...@ja...>]

I've added the FN_GROUP_INIT and modified Fltk::Group#begin
so that we can use the block instead of Group#end.

For example, we can write the following code:

Fltk::Pack.new(300,200){|pack|
  ...
}

The above is quit equal to the following code:

pack = Fltk::Pack.new(300,200)
...
pack.group_end
