TestExportTextLiteralAttributes and TestImportTextAttributes was failing because now we're assuming that BoxAlignment will have 1 of values from the list below and not "BoxAlignment"
"top-left", "top-middle", "top-right", "middle-left", "center", "middle-right", "bottom-left", "bottom-middle", "bottom-right"
Added drop down menu to Ifc Text section in object properties where you can change text's size and it will automatically change it in `EPset_Annotation.Classes`. You can also preview it in viewport and it will write in IFC only after you finish editing.
Still need to investigate `annotation.Annotator.resize_text(context.active_object)` in `refreshFontSize`.
1) Puts IFC Text only on top of ifc panels to make it easier to change it's text
2) I guess it could be a good practive to set `bl_order = 1` by default so it will be possible later to prioritize something since by default blender sets `bl_order = 0` and then even `bl_order = -1` wouldn't help.
3) May not work in previously created files
Currently it causes an error if you run it in object mode and doesn't really work in edit mode either because you may have no vertices selected. Will fix soon.
Now it's possible to set custom markers in section annotation.
To do so you need to add BBIM_Section pset to the annotation and then you can either toggle displaying some marker with ShowStartArrow/ShowEndArrow or you can write the id of some custom symbol in StartArrowSymbol/EndArrowSymbol (need to make sure the symbol is included in symbols.svg).
Other changes:
- removed vertex sorting in decoration.py so that start and end points will be the same thing both in svg and in viewport representation (previously the sorting was needed of the direction the arrow in shader wasn't inverted));
- fixed bug when in svg section arrow symbols wouldn't rotate if you move individual verts of the annotation, not the entire object (I guess this bug sneaked in after adapting elevation annotation)
Here's the example - https://i.imgur.com/db09OVF.png
To make it work need to add BBIM_Section property set to the annotation and set "HasConnectedSectionLine" to False (by default it's True).
Also added preview for this feature in viewport.
Otherwise it always returned a list with 1 empty string like `[ "" ]` which resulted in messy class names in svg like "-87IfcAnnotation0LtaLiEpzAOxEqmIvCV27EFALLSLOPEANGLE".
Added fall annotation - they appear both in viewport and svg.
There are three types of annotations (SLOPE_ANGLE, SLOPE_FRACTION, SLOPE_PERCENT) you can switch them by changing annotation's ObjectType to one of those values.
By default it uses angle representation.
