These procedures are identical to the Xlib procedures
    XCreatePixmap and XFreePixmap, except that they have extra
    code to manage X resource identifiers so that identifiers for deleted
    pixmaps can be reused in the future. It is important for Tk applications to
    use these procedures rather than XCreatePixmap and
    XFreePixmap; otherwise long-running applications may run out of
    resource identifiers.


Tk_GetPixmap creates a pixmap suitable for drawing in
    d, with dimensions given by width, height, and
    depth, and returns its identifier. Tk_FreePixmap destroys the
    pixmap given by pixmap and makes its resource identifier available
    for reuse.
