//
//	1. Enforce API surface and semantic compatibility with 1.9.x branch
//	2. Improve the module's maintainability by reducing the storage
//		paths to a single mechanism.
//	3. Use the same single mechanism to support "private" and "user" data.
//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//	5. Avoid exposing implementation details on user objects (eg. expando properties)
//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

     *
     * 1. Initialize the sizers's size to its size hint and compute the
     *    sums for each of size hint, min size, and max size.

     *    sizers to their min size and return.
     *
     * 4. If the available space is greater than the total max size, set
     *    all sizers to their max size and return.
     *
     * 5. If the layout space is less than the total size hint, distribute
     *    the negative delta as follows:
     *
     *    a. Shrink each sizer with a stretch factor greater than zero by
     *       an amount proportional to the negative space and the sum of
     *       stretch factors. If the sizer reaches its min size, remove
     *       it and its stretch factor from the computation.

     *    b. If after adjusting all stretch sizers there remains negative
     *       space, distribute the space equally among the sizers with a
     *       stretch factor of zero. If a sizer reaches its min size,
     *       remove it from the computation.
     *
     * 6. If the layout space is greater than the total size hint,
     *    distribute the positive delta as follows:
     *
     *    a. Expand each sizer with a stretch factor greater than zero by
     *       an amount proportional to the postive space and the sum of
     *       stretch factors. If the sizer reaches its max size, remove
     *       it and its stretch factor from the computation.
     *
     *    b. If after adjusting all stretch sizers there remains positive
     *       space, distribute the space equally among the sizers with a
     *       stretch factor of zero. If a sizer reaches its max size,
     *       remove it from the computation.
     *
     * 7. return
     *
     * @param sizers - The sizers for a particular layout line.
     *
     * @param space - The available layout space for the sizers.
     *

 * - `'p-drop'`- Dispatched when the mouse is released over the target
 *   element when the target indicates an appropriate drop action. If
 *   the event is canceled, the indicated drop action is returned to
 *   the initiator through the resolved promise.
 *
 * A drag operation can be terminated at any time by pressing `Escape`
 * or by disposing the drag object.
 *
 * A drag object has the ability to automatically scroll a scrollable
 * element when the mouse is hovered near one of its edges. To enable
 * this, add the `data-p-dragscroll` attribute to any element which
 * the drag object should consider for scrolling.
 *
 * #### Notes
 * This class is designed to be used when dragging and dropping custom
 * data *within* a single application. It is *not* a replacement for
 * the native drag-drop API. Instead, it provides an API which allows
 * drag operations to be initiated programmatically and enables the
 * transfer of arbitrary non-string objects; features which are not
 * possible with the native drag-drop API.

// a transform stream is a readable/writable stream where you do
// something with the data.  Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored.  (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation.  For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes.  When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up.  When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer.  When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks.  If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk.  However,
// a pathological inflate type of transform can cause excessive buffering
// here.  For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output.  In this case, you could write a very small
// amount of input, and end up with a very large amount of output.  In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform.  A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.
