When removing arbitrary fields from rows, any correlation between rows and/or columns will be lost. Is that acceptable?

xkbaddgeomoverlay
XkbAddGeomOverlay(3) XKB FUNCTIONS XkbAddGeomOverlay(3)
NAME
XkbAddGeomOverlay - Add one overlay to a section
SYNOPSIS
XkbOverlayPtr XkbAddGeomOverlay (XkbSectionPtr section, Atom name, int sz_rows);
ARGUMENTS
- section
section to which an overlay will be added
- name name of the overlay
- sz_rows
number of rows to reserve in the overlay
DESCRIPTION
Xkb provides functions to add a single new element to the top-level keyboard geometry. In each case the num_ * fields of the corresponding
structure is incremented by 1. These functions do not change sz_* unless there is no more room in the array. Some of these functions fill
in the values of the element's structure from the arguments. For other functions, you must explicitly write code to fill the structure's
elements.
The top-level geometry description includes a list of geometry properties. A geometry property associates an arbitrary string with an
equally arbitrary name. Programs that display images of keyboards can use geometry properties as hints, but they are not interpreted by
Xkb. No other geometry structures refer to geometry properties.
XkbAddGeomOverlay adds an overlay with the specified name to the specified section. The new overlay is created with space allocated for
sz_rows rows. If an overlay with name name already exists in the section, a pointer to the existing overlay is returned. XkbAddGeomOverlay
returns NULL if any of the parameters is empty or if it was not able to allocate space for the overlay. To allocate space for an arbitrary
number of overlays to a section, use the XkbAllocGeomOverlay function.
STRUCTURES
typedef struct _XkbOverlayRec {
Atom name; /* overlay name */
XkbSectionPtr section_under; /* the section under this overlay */
unsigned short num_rows; /* number of rows in the rows array */
unsigned short sz_rows; /* size of the rows array */
XkbOverlayRowPtr rows; /* array of rows in the overlay */
XkbBoundsPtr bounds; /* bounding box for the overlay */
} XkbOverlayRec,*XkbOverlayPtr;
