Draws part of an image (defined by the source rectangle
{@code (sx1, sy1, sx2, sy2)}) into the destination rectangle
{@code (dx1, dy1, dx2, dy2)}.  The destination rectangle is first
cleared by filling it with the specified {@code bgcolor}. Note that
the {@code observer} is ignored.

@param img  the image.
@param dx1  the x-coordinate for the top left of the destination.
@param dy1  the y-coordinate for the top left of the destination.
@param dx2  the x-coordinate for the bottom right of the destination.
@param dy2  the y-coordinate for the bottom right of the destination.
@param sx1 the x-coordinate for the top left of the source.
@param sy1 the y-coordinate for the top left of the source.
@param sx2 the x-coordinate for the bottom right of the source.
@param sy2 the y-coordinate for the bottom right of the source.
@param bgcolor  the background color ({@code null} permitted).
@param observer  ignored.

@return {@code true} if the image is drawn.
