// 7 january 2015
// TODO remove
#include <stdio.h>
// TODO
// - should tablePanic be CALLBACK or some other equivalent macro? and definitely export initTable somehow, but which alias macro to use?
// - make panic messages grammatically correct ("Table error: adding...")
// - make access to column widths consistent; see whether HDITEMW.cxy == (ITEMRECT.right - ITEMRECT.left)
// - make sure all uses of t->headerHeight are ADDED to RECT.top
// - WM_THEMECHANGED, etc.
// - see if vertical centering is really what we want or if we just want to offset by a few pixels or so
// - going right from column 0 to column 2 with the right arrow key deselects
// - make sure all error messages involving InvalidateRect() are consistent with regards to "redrawing" and "queueing for redraw"
// - collect all resize-related tasks in a single function (so things like adding columns will refresh everything, not just horizontal scrolls; also would fix initial coordinates)
// - checkbox columns don't clip to the column width
// - send standard notification codes
// - seriously figure out how we're going to update everything about the table in one place
