Please do not attempt to use this yet as it is a work in progress. Given
large number of merge conflicts, I pushed this partial commit to save time
rebasing.
All of the user interface is hidden behind the "EnableVariantUI" advanced
configuration flag until variants are ready.
This still leaves a few things out in the cold,
such as hit-testing and polygon generation.
But at least it allows us to plot with a default
font.
Fixes https://gitlab.com/kicad/code/kicad/-/issues/19031
Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
Also fixes a bug where ERC testing for text variables in sheet pins
would start with the wrong sheet.
Also fixes a bug where ERC testing of similar labels would use the
wrong sheet.
Also fixes a bug where ERC testing of bus-to-net conflicts would use
the wrong sheet.
Also fixes a bug where ERC didn't process variable references when
checking hierarchical labels against sheet pins.
Also fixes a bug where ERC multiple-drivers and netclass-conflicts
tests didn't set a sheetpath.
A sheetpath is required to correctly resolve text variables.
Depending on currentSheet is rife with bugs.
There are many places where we do *not* want to be prepending
field names to the field values, such as netlisting,
building PDF hypertext menus, etc.
Also, Find/Replace needs to work on unresolved text, as
that's what we're going to display (and if replace nuked
your variable references you wouldn't be happy).
Also moves most navigation code to SCH_NAVIGATION_TOOL.
Also changes page number href to anchor syntax ('#foo').
Also adds hypertext processing to SCH_TEXTBOXes.
Also adds combobox with schematic pages to text properties dialog.
And undo the previous changes in SCH_TEXT::Rotate().
We continue hitting this with a wrench until it gets fixed or becomes
broken beyond any recognition.
Global labels can optionally have intersheet references. When enabled,
they expand the bounding box of the label. Because they can be far away
from the actual label, the bounding box is not a good approximation for
the hittest
