Write an empty string as value to the keyring if None is parsed and
return a None value if an empty string was parsed from the keyring.
CURA-7180_keyring_none_value
If the range of the colour spectrum is 0, i.e. there is only one value for the current colour spectrum, then this would previously give a division by 0 in the shader, causing the final colour to become black. This is unexpected and makes the layer view hard to read. Instead, we'll now use the middle of the range then.
This was likely a problem for a long time but only really became visible due to the colour spectrum now showing only the range of values for the visible structures. Previously it was a problem e.g. for layer thickness if all layers had the same thickness (i.e. initial layer height == layer height).
The input array here is 2D, but always 1 by N long. The output of where then gives a tuple of two arrays, one indicating the Y positions and the other the X positions. The X positions were therefore always 0. The amin and amax functions were then always taking this index 0 along in their results, regardless of whether the line at that index was visible at all or not.
This will also improve performance since it's checking the limits now only for half as many indices.
This prevents previous measurements from influencing the colour scheme. Essentially previously it was showing the colour scheme based on all lines you had ever seen, rather than just the line types you were currently seeing.
If the user makes certain structures visible or invisible, and this then causes the limits of the colour scheme to change, this now triggers the layer view to be re-rendered and updates the legend in the simulation view menu component.
This is just a refactor that shouldn't have any influence on the behaviour.
It is a necessary prerequisite to be able to trigger the updating of the layer view colour spectrum more frequently, i.e. if the visible line types change.
This way, if travel moves are not currently visible in the layer view, the travel moves don't get counted with the limits to determine the colour spectrum to grade each line with. Quite often, travel moves had a much greater speed than other moves, like 120mm/s instead of the fastest printed line 60mm/s. This caused all of the layer view to be pushed into the lower end of the spectrum. It makes it hard to distinguish the differences in speed and line width because travel moves influence the spectrum so much. This way, the travel moves only influence the spectrum if they are visible. If they are visible, it might be relevant to the user. Otherwise, the user gets the full spectrum to differentiate between all the line widths and speeds.
This currently doesn't update correctly yet. That is something we'll need to fix.
All of our current layer view colour schemes are properties of a line, not of a vertex. The line has a single feedrate, a single line type, a single layer thickness, a single material colour and a single width. This is even limited by the g-code specification itself, which is unable to represent lines with varying line width. However, we store this information in the vertices, the vertex data being the only data sent to layer view since layer view is sent as polylines to the shader.
This change makes the entire line take on the colour scheme of the vertex where its representative data is stored. This data is intended for the line, not just for that vertex, so it makes sense that the entire line listens to the data of the correct vertex, not just the nearest vertex of the line's endpoint.
It is known that will cause some user scripts to default behaviour.
But this is accepted behaviour, and the benefits of not upgrading
the Cura Application version outweigh this.
Formerly this probably wasn't translated because it's like a name or term. But now it definitely needs to be translated.

It's now documented and written down in human terms. Since it doesn't involve encoding contours as 0-width paths any more, the rendering should also be a bit faster.

The actual package name internally will still have the spaces.
People were using this to get ahead in the sorting of packages, which is a little unfair. This doesn't make that impossible, but prevents it for the most part.
