<span class="c1"># 96-04-08 fl Created</span>
<span class="c1"># 96-09-06 fl Added getimage method</span>
<span class="c1"># 96-11-01 fl Rewritten, removed image attribute and crop method</span>
<span class="c1"># 97-05-09 fl Use PyImagingPaste method instead of image type</span>
<span class="c1"># 97-05-12 fl Minor tweaks to match the IFUNC95 interface</span>
<span class="c1"># 97-05-17 fl Support the "pilbitmap" booster patch</span>
<span class="c1"># 97-06-05 fl Added file= and data= argument to image constructors</span>
<span class="c1"># 98-03-09 fl Added width and height methods to Image classes</span>
<span class="c1"># 98-07-02 fl Use default mode for "P" images without palette attribute</span>
<span class="c1"># 98-07-02 fl Explicitly destroy Tkinter image objects</span>
<span class="c1"># 99-07-24 fl Support multiple Tk interpreters (from Greg Couch)</span>
<span class="c1"># 99-07-26 fl Automatically hook into Tkinter (if possible)</span>
<span class="c1"># 99-08-15 fl Hook uses _imagingtk instead of _imaging</span>
