* NEW: A new widget ReportDrawingArea allow to draw freely on
the report page. It have an event draw that provide the size of
the drawing (depending on the paint device resolution too.
Sometime you can use ReportUnits.DesktopScale ratio to fix
the size).
A cached property, allow to call the event only when the device
resolution change, it is usefull when a draw need a lot of
computing.
* NEW: MTool and Units have been merged to create a new shared
module: ReportUnits. It provide functions for unit convertions
depended on paint resolution (for pixel convertion use it in a
paint session)
A property DesktopScale provide a ratio between Desktop pixel
size and printer size.
* BUG: Add again forgotten files.
