Summary0013141: Cube Axis has font size weirdness
DescriptionThe cube axis has a font size weirdness. It may be hard to replicate.
* Linux, master, local server.
* Open Can.exo. Apply.
* Show cube axis.
* Reset, +Z.
* Now, single step forward. At timestep 17 number, on the Y-Axis, -1.00 appears, all the numbers are on top of each other, and the font becomes larger/bolder. This is the bug.

 By the way, the reason the previous functionality is obnoxious is that during a movie, the cube axis will tend to bounce.

Another place this shows up is with disk_out_ref.exo.

Open disk_out_ref.exo.
Turn on Show cube axis.
+Z
The Y axis labels will change size.

 This could be replicated. The general observation is that whenever there is a transitions then the font size briefly changes.

This could be because of a number of reasons.

 reopening since the font weridness exists. It does go away once we swicth to using FreeType based text, but that needs more work to ensure it continues to render correctly even for small text.

 To enable FreeType font in cube axes just add the following line

    Use TextActor3D for CubeAxes representation
    
    The titles and labels are smoother with UseTextActors3D

 Marking todo, since this is hurting one of my users.

 I encountered this same bug when implementing a mode where the axes change size to stay within the viewport. The underlying problem was that when the number of numeric labels changed, the position of the labels was not set prior to computing the label size, causing the jump in font size in the first render after the number of labels changed. You'll notice that in Alan's steps to reproduce, the label size jumps at timesteps in the dataset where the number of labels along an axis direction changes. During subsequent renderings, the label position would get set and the label size would be correct, making this bug a little tricky to characterize and track down.

The bug is fixed in this VTK commit:

I verified that this change fixes the error produced by Alan's bug report. Note that this change is not yet available in ParaView master, but should hopefully make it in after the next gatekeeper review.
