Bug Description

Currently, there is a nice helper box displayed beside the cursor when drawing an arc. I would consider it as useful to also add it to the other graphical objects as well:

Line: length and angle starting from the last point
Circle: radius
Polygone: length and angle starting from the last point (or probably to both connected points)

Probably the same for zones and keep out areas as for polygons

I did a first implementation of this issue to add status popups to segments and circles.

To achieve this I used the Arc implementation as a blueprint and found out that draw segment lacks a geometric manager. My current implementation of the geometric manager is tied to the visualization part, but I suspect the geometric manager is normally used for more parts of the drawing step.

I didn't want to break anything, so I did not changed the drawSegment Implementation to use the geometric manager for more fundamental things. In the future this should probably be adopted.

Patches can also be found on:

(Please note, there is another commit in this repo which fixes some spelling issues in the ARC_ASSISTANT)

Known issues of this patches:

* when drawing multiple lines, the popup only appears after moving the mouse slightly
* when drawing multiple lines, the popup always jumps to the lower left side of the cursor as long as it knows no direction.

For the first issue, I have no Idea why it is there. Probably the mouse movement causes the restart of the tool or something like that.

For the second one: the Geometric Manager does not know the last drawn line, which would be a useful hint in the future to prevent those text jumps.

I rebased the branch to the current master and fixed a little bug which was exposed by this patchset.

Another Issue found (probably related to the new snapping-feature):

* drawing a triangle results in a selection dialogue appearing when finishing the last line.
