This function creates a <a class="link" href="libgimp-gimpdrawable.html#GimpDrawable" title="GimpDrawable"><span class="type">GimpDrawable</span></a> structure for the core
drawable identified by <em class="parameter"><code>drawable_ID</code></em>. The returned structure
contains some basic information about the drawable and can also
hold tile data for transfer to and from the core.
</p>
<p>
Note that the name of this function is somewhat misleading, because
it suggests that it simply returns a handle.  This is not the case:
if the function is called multiple times, it creates separate tile
lists each time, which will usually produce undesired results.

This procedure fills the drawable. If the fill mode is foreground
the current foreground color is used. If the fill mode is
background, the current background color is used. If the fill type
is white, then white is used. Transparent fill only affects layers
with an alpha channel, in which case the alpha channel is set to
transparent. If the drawable has no alpha channel, it is filled to
white. No fill leaves the drawable's contents undefined. This
procedure is unlike the bucket fill tool because it fills regardless
of a selection. Its main purpose is to fill a newly created drawable
before adding it to the image. This operation cannot be undone.

<p>
Find the bounding box of the current selection in relation to the
specified drawable.
</p>
<p>
This procedure returns whether there is a selection. If there is
one, the upper left and lower right-hand corners of its bounding box
are returned. These coordinates are specified relative to the
drawable's origin, and bounded by the drawable's extents. Please
note that the pixel specified by the lower right-hand coordinate of
the bounding box is not part of the selection. The selection ends at
the upper left corner of this pixel. This means the width of the
selection can be calculated as (x2 - x1), its height as (y2 - y1).
Note that the returned boolean does NOT correspond with the returned
region being empty or not, it always returns whether the selection
is non_empty. See <a class="link" href="libgimp-gimpdrawable.html#gimp-drawable-mask-intersect" title="gimp_drawable_mask_intersect ()"><code class="function">gimp_drawable_mask_intersect()</code></a> for a boolean
return value which is more useful in most cases.

This procedure offsets the specified drawable by the amounts
specified by 'offset_x' and 'offset_y'. If 'wrap_around' is set to
TRUE, then portions of the drawable which are offset out of bounds
are wrapped around. Alternatively, the undefined regions of the
drawable can be filled with transparency or the background color, as
specified by the 'fill-type' parameter.
