A layout consists of which windows are in // which rows, row sizes and other general state tracking that would make // calculating window positions from this information fairly easy. // // After a layout is computed that's considered the best layout, we // compute the layout scale to fit it in the area, and then compute // slots (sizes and positions) for each thumbnail. // // Layout generation // ----------------- // // Layout generation is naive and simple: we simply add windows to a row // until we've added too many windows to a row, and then make a new row, // until we have our required N rows. The potential issue with this strategy // is that we may have too many windows at the bottom in some pathological // cases, which tends to make the thumbnails have the shape of a pile of // sand with a peak, with one window at the top. // // Scaling factors // --------------- // // Thumbnail position is mostly straightforward -- the main issue is // computing an optimal scale for each window that fits the constraints, // and doesn't make the thumbnail too small to see. There are two factors // involved in thumbnail scale to make sure that these two goals are met: // the window scale (calculated by _computeWindowScale) and the layout // scale (calculated by computeSizeAndScale). // // The calculation logic becomes slightly more complicated because row // and column spacing are not scaled, they're constant, so we can't // simply generate a bunch of window positions and then scale it. In // practice, it's not too bad -- we can simply try to fit the layout // in the input area minus whatever spacing we have, and then add // it back afterwards. // // The window scale is constant for the window's size regardless of the // input area or the layout scale or rows or anything else, and right // now just enlarges the window if it's too small. The fact that this // factor is stable makes it easy to calculate, so there's no sense // in not applying it in most calculations. // // The layout scale depends on the input area, the rows, etc, but is the // same for the entire layout, rather than being per-window. After // generating the rows of windows, we basically do some basic math to // fit the full, unscaled layout to the input area, as described above. // // With these two factors combined, the final scale of each thumbnail is // simply windowScale * layoutScale... almost. // // There's one additional constraint: the thumbnail scale must never be // larger than WINDOW_PREVIEW_MAXIMUM_SCALE, which means that the inequality: // // windowScale * layoutScale <= WINDOW_PREVIEW_MAXIMUM_SCALE // // must always be true. This is for each individual window -- while we // could adjust layoutScale to make the largest thumbnail smaller than // WINDOW_PREVIEW_MAXIMUM_SCALE, it would shrink windows which are already // under the inequality.
