Before, syntax patterns/regexes that started with `^` didn't have the
desired effect of matching with the start of the line.
Now those patterns are used only when matching the whole line.
Before, if `offset > 1` was used, the match would have failed because
the beginning of the string was never met.
Now we force the beginning of the string to be the one specified by the
offset.
* Items are now objects that can be retrieved and manipulated.
* clip rect is used for left and right panes
* initial support for items to do their own custom drawing by also
doing a clip rect for them
* a custom background color can be specified for the item.
* a command or function can be executed on item click.
* Introduced functionality to easily hide or show all or specific items.
* Better handling of deprecated get_items()
* Spacing is automatically added to items and cleaned on deprecated
items.
* Default items where separated and given the names:
doc:file, doc:position, doc:indentation, doc:lines,
doc:line-ending, core.commandview.
* Some default right or left click actions where given to the default
items.
* Started adding required bits to support dragging to left and right
panes when some items aren't visible.
Note: should work well enough already but maybe some repetitive stuff can be
cleaned out.
* Support for predicates by introducing add_item().
* Support for performing click actions on items.
* Support for optional tooltips on item hover.
* Deprecate the usage of get_item().
* Fixed rendering computations for y offset.
* Force monospacing if every ascii character has the same integer advance.
* Added in explanatory comment.
* Fixed issues.
* Made lines less long.
The pattern cannot be tested in advance as it seems that Lua inspect
the pattern only partially, the part that is actually used.
We resort to use pcall to catch any error when using the pattern.
This is needed for example when a selection has both `line1` and `col1`
at 1, and the left arrow is pressed: `line2` and `col2` change, while
`line1` and `col1` don't, but we still want to scroll.
