Retain cycle

[coppercash]

Hi,
Thanks for the excellent work.
I found a "retain cycle".
IDMZoomingScrollView -> IDMPhoto -> IDMProgressUpdateBlock -> IDMZoomingScrollView

- (void)configurePage:(IDMZoomingScrollView *)page forIndex:(NSUInteger)index {
    page.frame = [self frameForPageAtIndex:index];
    page.tag = PAGE_INDEX_TAG_OFFSET + index;
    page.photo = [self photoAtIndex:index];

    __block __weak IDMPhoto *photo = (IDMPhoto*)page.photo;
    photo.progressUpdateBlock = ^(CGFloat progress){
        [page setProgress:progress forPhoto:photo];
    };
}

Should use a '__weak' ref for page involved in the block above, or break the cycle in method unloadUnderlyingImage.

Fixed! It will be in the next version. Thanks!
