offset get values

[GoogleCodeExporter]

hi,

i'm adding some additional function to have the possibility to shift the
zoom croped result image vertical a later maybe horizontal too.

added line 34: 
$zoom_crop_offset_y = preg_replace( "/^[1-9][0-9]*$/", "", get_request(
'zcoy', 0 ) );

modification an line 365:
$cachename = get_request( 'src', 'timthumb' ) . get_request( 'w', 100 ) .
get_request( 'h', 100 ) . get_request( 'zc', 1 ) . get_request( 'q', 80 ) .
get_request( 'zcoy', 0 );

add line 92:
$offset_y = $zoom_crop_offset_y;

and mod line 108:
$src_y = round( ( $height - ( $height / $cmp_y * $cmp_x ) ) / 2 ) + $offset_y;


all done with less knowhow, and a much try and error and very much google :-)

enagble to set a &zcoy=value (pixels) can my positiv or negative value to
shift the croped result verticaly
