[Tilecache] cells not being calculated correctly for bounding box

[Frédéric Junod]

Hi,

Just tested the trunk version and http://trac.tilecache.org/changeset/385
breaks my config: I always have the "Current x value XXX is too far from tile
corner x XXX" error.

my layer definition:

[kanton]
type=MapServer
mapfile=/foo/bar/chtopo_tilecache.map
srs=EPSG:21781
bbox=420000,30000,900000,350000
resolutions=650,500,250,100,50,20,10,5,2.5,2,0.5
extension=png
mime_type=image/png; mode=32bit

Reverting the change fixes the problem.
