Description Jessy Mallet CLA 2017-11-09 07:00:34 EST 
In order to control resolution of image and time to export diagram, a scale level should be add on export diagram popup and Sirius diagram preference page.

If _Auto-scale_ is checked with level to 100%, diagram will be scaled to the maximum possible size. This can produce higher resolution images in long time.
If _Auto-scale_ is checked with level to 0%, diagram will be not scaled. Images will be produced with lower resolution but also with shorter time.
This new parameter allows you to choose the tradeoff you want.

Manual Scenario to reproduce :
 * import the attached testSizeLevel project in your workspace,
 * In the preferences page Sirius > Sirius Diagram, make sure that the "Size of exported image" is set to Max (default value) and choose level size to nominal,
 * Open the session and launch "Export representations as image" action
    -> The export dialog box has the "Image Size" set to nominal
    -> Diagrams are exported quickly in nominal resolution (35 images of 391Ko)
 * Launch Export representations as image action and set the size to middle between nominal and Max
    -> Diagrams are exported in middle resolution but with longer time (35 images of 21.9Mo exported in around 45 seconds)
 *  In the preferences page Sirius > Sirius Diagram, make sure that the "Size of exported image" is set to Nominal and choose level size to Max,
 * Open the session and launch "Export representations as image" action
    -> The export dialog box has the "Image Size" set to max
    -> Diagrams are exported slower than previously but with better resolution (35 image of 57.1 Mo exported in around 2min30)
