Mir related performance items
This blueprint contains elements for mir performance investigation & implementation activities. This should encompass performance optimizations which are either generic in nature and/or specific to any of the form factors; smartphone, tablet, or desktop. Note, I would encourage performance activities which do not involve mir (e.g. xmir or rootless x on mir) to be tracked in another blueprint.
