-# Map symbolic cursor names to platform-appropriate cursors.
-#
-# The following cursors are defined:
-#
-# standard -- default cursor for most controls
-# "" -- inherit cursor from parent window
-# none -- no cursor
-#
-# text -- editable widgets (entry, text)
-# link -- hyperlinks within text
-# crosshair -- graphic selection, fine control
-# busy -- operation in progress
-# forbidden -- action not allowed
-#
-# hresize -- horizontal resizing
-# vresize -- vertical resizing
-#
-# Also resize cursors for each of the compass points,
-# {nw,n,ne,w,e,sw,s,se}resize.
-#
-# Platform notes:
-#
-# Windows doesn't distinguish resizing at the 8 compass points,
-# only horizontal, vertical, and the two diagonals.
-#
-# OSX doesn't have resize cursors for nw, ne, sw, or se corners.
-# We use the Tk-defined X11 fallbacks for these.
-#
-# X11 doesn't have a "forbidden" cursor (usually a slashed circle);
-# "pirate" seems to be the conventional cursor for this purpose.
-#
-# Windows has an IDC_HELP cursor, but it's not available from Tk.
-#
-# Tk does not support "none" on Windows.
