[ptx] huigin somes bugs

[Ph. Gac]

hi,

it seems hugin doesn't save optimization state for d, e

btw, there is trouble, also, with "inherit" flag which doesn't change the checkboxes on optim page page accordingly

after "new", CPs from last current pair of pages are still displayed (in list, and as circles on the blank zone!)

image cache is not actualized when an image is removed and then reloaded (after being modified); click second point in
grey zone or a place that doesn't "exist" any more  causes abnormal program termination

regards,

philippe
