Rendering problems of IRS group brackets

[epruesse]

The third type (not radial, not normal, not list) shows the topmost group in demo.arb wrongly. It's just a line, the sequences aren't shown. (Happens in trunk also). When folded, the group appears normally.

• group is named 'outer' in my version (also displays as 'outer' both in trunk and gtk)
• display in trunk is perfect for me. when the group is open, it displays a kind of bracket enclosing the group (shaped similar to character '['). The line you saw is just the upper horizontal line of the group.
  Annotation:
  • The intention of that mode (called IRS) is to show the complete hierarchy of the shown part of the . Unfold group 'g2' and 'outer' and move the upwards to get an impression.
  • IRS is an acronym still searching its full name
• gtk version has the following differences:
  • brackets enclosing open groups are not drawn with dotted lines (so you cannot tell them apart from structure)
  • the upper horizontal line of the bracket of the 1st group is drawn bold

I had a quicksave, must have changed it at some point to test renaming groups.

Like AISC then…

It works with AA turned off…

The entire world/device/pixel mapping/scaling issue seems to be more than a bit complicated. ARB positions center on pixels, Cairo positions center between pixels. According to Cairo FAQ appropriate rounding needs to be done depending on the situation (filled areas are different than lines, zooming and antialiasing complicate things).

Since I don't want to mess with this too much just now, I'll just make the dotted line use short 2px dashes separated by 2px (the dashed line uses 3px distance and 8px lines).

Looks nice now
