memory leaks (LaternaMagica)

[Riccardo Mottola]

Hi,

I noticed a quite evident memory leak in LaternaMagica.

1) add a bunch of images to your list
2) export images to a folder. Use standard settings (TIFF, no resizing)

At the end,  memory increase might increase significantly if you had 
very big images or many of them.

Making another export, just increases memory more, so it is not reused.

- I'm pretty sure it used to work fine. I allocate my own memory pool to 
drain it regularly, so that the peak consumption is not too high. 
However, even before the change, usage peaked, but everything got released
- On the mac there is no evident leakage

Any hints, helps... I have no clue yet "what" gets leaked, since it 
doesn't leak on the mac and the memory panel looks buggy... with 
negative values. Also it is a count only.. here we speak about big 
chunks of ram, perhaps of few objects.
