Log:
- added text renderer
- non-filled arrows are now open
- added measurements (syntax: meas <point-a> <point-b> <offset>)
- we now draw frame titles

+Measurements
+- - - - - -
+
+Measurements show the distance between two points:
+
+meas <point-a> <point-b> <offset>
+
+The offset is the distance from the imaginary line connecting points A
+and B the measurement line is draw:
+
+- if the offset is 0mm, the line will connect A and B
+- if the offset is positive, the line would be on the left-hand side when
+ traveling from A to B
+- if the offset is negative , the line would be on the right-hand side when
+ traveling from A to B
+
+Example:
+
+a: vec @(-1mm, 1mm)
+b: vec @(1mm, 1mm)
+meas a b 0.2 mm

- add table/var/loop editor (missing: add col/row, add/del var/table/loop)
- add default unit (combine with grid unit selection ?)
- consider adding auto/mm/mil selection for each dimension
