Check if the image's undo stack is enabled.
</p>
<p>
This procedure checks if the image's undo stack is currently enabled
or disabled. This is useful when several plugins or scripts call
each other and want to check if their caller has already used

<p>
Freeze the image's undo stack.
</p>
<p>
This procedure freezes the image's undo stack, allowing subsequent
operations to ignore their undo steps. This is generally called in
conjunction with <a class="link" href="libgimp-gimpundo.html#gimp-image-undo-thaw" title="gimp_image_undo_thaw ()"><code class="function">gimp_image_undo_thaw()</code></a> to temporarily disable an

<a class="link" href="libgimp-gimpundo.html#gimp-image-undo-enable" title="gimp_image_undo_enable ()"><code class="function">gimp_image_undo_enable()</code></a> differ in that the former does not free up
all undo steps when undo is thawed, so is more suited to interactive
in-situ previews. It is important in this case that the image is
back to the same state it was frozen in before thawing, else 'undo'
behaviour is undefined.

<p>
Thaw the image's undo stack.
</p>
<p>
This procedure thaws the image's undo stack, allowing subsequent
operations to store their undo steps. This is generally called in
conjunction with <a class="link" href="libgimp-gimpundo.html#gimp-image-undo-freeze" title="gimp_image_undo_freeze ()"><code class="function">gimp_image_undo_freeze()</code></a> to temporarily freeze an
image undo stack. <a class="link" href="libgimp-gimpundo.html#gimp-image-undo-thaw" title="gimp_image_undo_thaw ()"><code class="function">gimp_image_undo_thaw()</code></a> does NOT free the undo
stack as <a class="link" href="libgimp-gimpundo.html#gimp-image-undo-enable" title="gimp_image_undo_enable ()"><code class="function">gimp_image_undo_enable()</code></a> does, so is suited for situations
where one wishes to leave the undo stack in the same state in which
one found it despite non-destructively playing with the image in the
meantime. An example would be in-situ plugin previews. Balancing
freezes and thaws and ensuring image consistancy is the
responsibility of the caller.
