Detailed Description

We keep a double reference of thumbnail objects for the current collection:

as a hash table keyed by imgid, in table->list
as an array of fixed length, in table->lut.

The hash table is used to keep track of allocated objects to update, redraw and free. Its length is limited to 840 elements or whatever is visible inside viewport at current scroll level. It's garbage-collected.

The LUT is used to speed up lookups for thumbnails at known, bounded positions in sequential order (position in collection = (rowid - 1) in SQLite result = order in GUI = index in the LUT). This LUT prevents us from re-querying the collection in SQLite all the time using: "SELECT rowid, imgid FROM main.collected_images WHERE rowid > min_row AND rowid <= max_row ORDER BY rowid ASC". Note though that SQLite starts indexing at 1, so there is an unit offset. It also keeps a reference to the thumbnail objects, but objets should never be freed from there. Given that collections set on root folders contain all the images from their children, the number of elements in a LUT can be anything from 1 to several 100k images.

It is expected that thumbnails alloc/free always happen using table->list, and that table->lut only updates its references accordingly, because table->list gives us O(1) lookup by imgid and keeps iteration bounded to visible thumbnails.

Keep that in mind if/when extending features.

For image collections having up to 1000 items, we could just statically reset/init the list of thumbnails once when the collection changes, then only resize thumbnails at runtime. But for collections of thousands of images, while adding child widgets is fairly fast, considering, detaching those widgets from the parent takes ages (several orders of magnitude more than attaching). So we have no choice here but to attach and detach dynamically, as to keep the number of children reasonable. "Reasonable" is we populate the current viewport page (at current scrolling position), the previous and the next ones, as to ensure smooth scrolling.

The dimensions of the full collection grid are only ever virtual, but we need to make them real for the scrollbars to behave properly through dynamic loading and unloading of thumbnails. So we set the grid area to what it would be if we loaded all thumbnails.
