values are used.
XRecolorCursor can generate a BadCursor error.
The XFreeCursor function deletes the association between the
cursor resource ID and the specified cursor. The cursor
storage is freed when no other resource references it. The
specified cursor ID should not be referred to again.
XFreeCursor can generate a BadCursor error.
Some displays allow larger cursors than other displays. The
XQueryBestCursor function provides a way to find out what
size cursors are actually possible on the display. It
returns the largest size that can be displayed.
Applications should be prepared to use smaller cursors on
displays that cannot support large ones.
XQueryBestCursor can generate a BadDrawable error.
