The shape of the complex field to be displayed.
If true, display in MODE 2 as pseudo vectors in a (row, column) plane; if false, display is MODE 1 in polar coordinates assuming a conventional x, y plane.
Draw the single field element at the given indices.
Draw the single field element at the given indices.
Called after the pen has been moved to the top-left corner of the cell to draw in. Clients should take care to draw within the bounds of the cell, which is a cellSize by cellSize square.
It would be nice if we could give an element as an argument instead of a bunch of indices, but the Field class doesn't currently define any means to actually extract elements from the field; that's left to subclasses. Further complicating things, the panel classes don't know in advance how many dimensions the data field has, so we have to use a variable length indices parameter. If your field class has a read(indices: Int*) method, you can get the current element, regardless of field dimensions, like so:
val element = read(indices: _*)
A list of properties that should be persisted when the app closes, and restored the next time it's launched.
A list of properties that should be persisted when the app closes, and restored the next time it's launched. A common example of a persistent is the zoom/magnification level of the viewer. Be sure to add any relevenant properties to this list in your Viewer subclasses!

Compute any needed statistics on your data (for display or to help draw later). Called after new data has been received (in updateData) and before drawing begins for that new data.

Increase zoom level by zDelta.
Increase zoom level by zDelta.
Default zoom/unzoom increment used by zoomIn and zoomOut.
Default zoom/unzoom increment used by zoomIn and zoomOut. When the
ZoomType is Additive, this value is added to or substracted from the
current zoomLevel. In multiplicative mode, zoomLevel is multipled by
zDelta on zooming in or by its reciprocal on zooming out.
Decrease zoom level by zDelta.
Decrease zoom level by zDelta.
Controls how zDelta is applied to the current zoom level.
Controls how zDelta is applied to the current zoom level. In Additive, a delta is added to the current zoom level; in Multiplicative mode, the zoom level is multiplied by delta when zooming in, and by its reciprocal when zooming out.
Default zoom type is additive. If you change it to multiplicative, you should probably ensure that the default zDelta is something other than 1f, as multiplying by one probably won't do anything.
Subpanel which displays each number in a complex field in polar coordinates (as an arrow).
There are two modes here.
************************************************************** MODE 1: Standard complex number representation in an (x, y) plane.
This assumes a conventional (x, y) right-handed coordinate system for displaying each individual complex number. This means that:
2. Complex(0, 1) with point up
3. Complex(-1, 0) will point left
4. Complex(0, -1) will point down
************************************************************** MODE 2: As pseudo vectors in the (row, column) plane.
It is sometimes useful to use complex numbers as tiny vectors in a 2D field. You must be careful in doing that, though, because Cog uses a left-handed (row, column) coordinate system. In this mode, the real part of the number as treated as a row coordinate, and the imaginary part is treated as the columns coordinate. This means that:
2. Complex(0, 1) with point right
3. Complex(-1, 0) will point up
4. Complex(0, -1) will point left
