DESCRIPTION
The

CursorShape,
this is the largest size that can be fully displayed on the screen specified by
which_screen.
For
TileShape,
this is the size that can be tiled fastest.
For
StippleShape,
this is the size that can be stippled fastest.
For
CursorShape,
the drawable indicates the desired screen.
For
TileShape
and

the drawable indicates the screen and possibly the window class and depth.
An
InputOnly
window cannot be used as the drawable for
TileShape
or
StippleShape,
or a
BadMatch

XQueryBestSize
can generate
BadDrawable,
BadMatch,
and
BadValue
errors.
The
XQueryBestTile
function returns the best or closest size, that is, the size that can be
tiled fastest on the screen specified by which_screen.
The drawable indicates the screen and possibly the window class and depth.

DIAGNOSTICS
BadMatch
An
InputOnly
window is used as a Drawable.
BadDrawable
A value for a Drawable argument does not name a defined Window or Pixmap.
BadMatch
The values do not exist for an

BadValue
Some numeric value falls outside the range of values accepted by the request.
Unless a specific range is specified for an argument, the full range defined
by the argument's type is accepted. Any argument defined as a set of
