[Sugar-devel] [PATCH] sugar-session: disable Metacity mouse button modifiers (OLPC#11781)

[Daniel Drake]

Metacity provides "mouse button modifier" functionality which lets
you drag activity windows around the screen, amongst other things.
This is something we want to disable, similar to how we disable
metacity's key bindings.

In recent metacity releases, Alt is the default mouse button modifier.
We especially want to disable this functionality in this case because
Sugar uses Alt for other things, such as launching a new activity
instance (rather than a journal entry) from the home screen.
