bwselect and bwfill image toolbox bug

[Rosen Diankov]

hi all,

bwselect calling conventions are:
 [IMOUT, IDX] = bwselect(IM, COLS, ROWS, CONNECT)

and bwfill calling conventions are:
 [BW2, IDX] = bwfill(BW1, R, C, N)

Notice how the columns and rows are flipped. This is a *big* problem
because bwselect happily calls bwfill with inputting its columns
before rows. This causes octave to crash with memory corruption.

Another problem is possible compatibility issues with matlab because
matlab's bwfill function is
 [BW2, IDX] = bwfill(BW1, C, R, N)

this is tested with the newest release of the image toolbox 1.0.8
