Vadim Zeitlin 3f66f6a5b3 Remove all lines containing cvs/svn "$Id$" keyword.
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.

If nothing else, this will make an eventual transition to Git simpler.

Closes #14487.

/*
The wxListCtrl can show lists of items in four different modes:
wxLC_LIST: multicolumn list view, with optional small icons (icons could be
optional for some platforms). Columns are computed automatically,
i.e. you don't set columns as in wxLC_REPORT. In other words,
the list wraps, unlike a wxListBox.
wxLC_REPORT: single or multicolumn report view (with optional header)
wxLC_ICON: large icon view, with optional labels
wxLC_SMALL_ICON: small icon view, with optional labels
You can change the style dynamically, either with SetSingleStyle or
SetWindowStyleFlag.
Further window styles:
wxLC_ALIGN_TOP icons align to the top (default)
wxLC_ALIGN_LEFT icons align to the left
wxLC_AUTOARRANGE icons arrange themselves
wxLC_USER_TEXT the app provides label text on demand, except for column headers
wxLC_EDIT_LABELS labels are editable: app will be notified.
wxLC_NO_HEADER no header in report mode
wxLC_NO_SORT_HEADER can't click on header
wxLC_SINGLE_SEL single selection
wxLC_SORT_ASCENDING sort ascending (must still supply a comparison callback in SortItems)
wxLC_SORT_DESCENDING sort descending (ditto)
Items are referred to by their index (position in the list starting from zero).
Label text is supplied via insertion/setting functions and is stored by the
control, unless the wxLC_USER_TEXT style has been specified, in which case
the app will be notified when text is required (see sample).
Images are dealt with by (optionally) associating 3 image lists with the control.
Zero-based indexes into these image lists indicate which image is to be used for
which item. Each image in an image list can contain a mask, and can be made out
of either a bitmap, two bitmaps or an icon. See ImagList.h for more details.
Notifications are passed via the wxWidgets 2.0 event system, or using virtual
functions in wxWidgets 1.66.
See the sample wxListCtrl app for API usage.
TODO:
- addition of further convenience functions
to avoid use of wxListItem in some functions
- state/overlay images: probably not needed.
- in Win95, you can be called back to supply other information
besides text, such as state information. This saves no memory
and is probably superfluous to requirements.
- testing of whole API, extending current sample.
