Implements an alternate way to produce Interpress masters from ChipNDale drawings. The difference is in the user interface. It is similar to the one in programs by Imaging Folks, and it is simpler to use for casual users.

Implementation note on clipping: If bands have to be created because of the size of the design, true clipping to bands must be done when traversing the design. The penalty on the corner stitched data structure may be swallowed, since it is an overnight job anyway. However, leaving clipping to the Imager, you will have all those rectangles in the Interpress master with their multiciplity. A large disk can hold only about 90% of a thing like the Cross-RAM, and every single file on your disk will have been flushed off when you come in in the morning.
If you insist on leaving the clipping to the imager, then you must be very careful deciding where to place it. The reason is that clipping in the Imager is relative, and therefore the window must be specified inside Do-Save-Simple-Body, in order not to disturb the global clipping window. The places would be EnumerateGeometry and EnumerateTextInDesign.

Produces an Interpress master of the design. The master is scaled such that it fits a whole page. chipNDaleWindow is either the bounding box of the design or a window in it. In the latter case, clip must be set to TRUE, and objects completetly outside the window will be ommitted from the Interpress master (because of things like mitering, actual clipping can be performed only when a bitmap is created).
The usedField is specified in millimetres. It is useful for subsequent processing of the Interpress master as long as this field cannot be specified in the preamble of Interpress masters themselves.
If onlySel is true, only the selected object are included in the Interpress master.
If lambda = 0 then scale such that the window fills the field, else scale such that 1 will be lambda mm in the Interpress master.
May return signal tooComplex if it is believed that there might be too many rectangles in a horizontal cross section. The used criterion is the width of the design; if you do not agree, use the Interpreter to increase the risk.

Preview considers the top of the page to be most important, because we write text from top to bottom. Also designers want have images to be flush to the top of the field, so they can use the bottom of the medium for hand-annotations. Unfortunately, this causes a severe problem when producing a PD file. In fact there is said to be a hack fixing a hard bug in the Peach software. This hack is said to be a white rectangle at the lower left corner of the medium. On the Versatec this means that with every image in landscape format you would get metres of white paper. This is why images are positioned in the lower left corner of the field.

This is nasty code. The trade off was between sort of a hack, 20 minutes of CPU on full chips, and this fix here. I wanted to find all fonts appearing in the design in order to declare them in the preamble. The most stupid thing somebody could do, would be to use a ChipNDale drawProc to visit all text objects [this can take 20 minutes of CPU]. In fact you only need to visit once every object. In ChipNDale you do this by enumerating the directory. Unfortunately ChipNDale has one object which is never in the directory, namely the root cell. In order to avoid the unesthetic special code for the root, the fonts used in the root object are not cached. In the normal case, no fonts are missed, because if there are non-cell objects in the root then usually they have some buddy inside an official cell. So all this was to justify why the print font can be L and has to be handled here at this stange place. All in all I don't care, so if you want to do something different just go ahead (the quickest would be to bypass the ChipNDale directory enumeration procedure and to do your own; this is easy if you use my table called visitedCells).

Made a change to avoid anti-aliasing. All rectangles are now printed with the lower left corner starting on a pixel.
changes to: DIRECTORY, PrintAlignedTile, MaskAlignedRectangle (local of PrintAlignedTile), PrintTile, PrintBand, EnumerateGeometry (local of PrintBand)
gbb September 4, 1986 5:51:47 pm PDT
Changed the border of cells from a sequence of rectangles to a trajectory.
changes to: DIRECTORY, IMPORTS, DrawObjectBorder, DotDotDotSpace (local of DrawObjectBorder), DrawObject
gbb September 5, 1986 11:09:19 am PDT
Added the parameter sizeHint to the print procedure.
changes to: PeachProcess, Print

Black toner for color Versatec had gone lost somewhen.
changes to: PeachProcess
gbb September 22, 1986 3:26:33 pm PDT
Added capability to produce tone separations for PlateMaker.
changes to: DIRECTORY, PeachProcess, Print
gbb September 23, 1986 6:04:17 pm PDT
Addded filled trajectories.
changes to: DIRECTORY, DrawArea, DrawObjectBorder, DrawObject

Fixed scaling for devices with cut paper. Changed colour model used to print black. Added 1 to the height of bands.
changes to: DIRECTORY, DrawToIP (local of DoInterpress), black, unColour, BlendColours, PeachProcess.
gbb September 25, 1986 8:00:34 pm PDT
Bypassed an arcane bug in the compiler.
changes to: PeachProcess: see implementation note.
gbb October 2, 1986 1:01:19 pm PDT
Introduced a mild temporary hack to fix a server locking problem until the new print server software becomes available in about three to four weeks.
Finished adjusting and testing all the little details to print on Platemaker at 1200 lines per inch resolution. Instructions are written in the Terminal viewer. When submitting the separations, please advise the operator that the separations make use of the full device size.
changes to: Action (local of DoInterpress), PeachProcess

Tweeking the rendition of colours on the Versatec.
changes to: PeachProcess

Handle gracefully the limit of 50 entries in the Interpress frame.
changes to: DIRECTORY, Action (local of DoInterpress)

Added Raven 384 printer
changes to: PeachProcess, Print.

In ChipNdale 23 cut (cut-2) was always black (blue), but in rel. 24 was displayed black (blue) and printed blue (green).
changes to: SetLayerColourTable: cut is forced to black and cut-2 to blue.

In mid-december 1986, the Interpress to PD software has changed, and the speed-up trick of turning off the Interpress imaging model for the tesselated geometry does no longer work. The new regime is: the imager priority is always set to important, but setting NectarineImpl.layoutOnly ← TRUE in the interpreter, the priority is turned off. In addition rectangles are no longer aligned to pixels, avoiding the white strikes.

Since gates are very important, they are given double weight.
changes to: doubleYellowRGB: doubled, BlendColours: double weight for gates.
gbb February 2, 1987 6:02:40 pm PST
Added the capability to print at a given scale, i.e., to define in millimetres
changes to: DoInterpress added parameter lambda, DrawToIP (local of DoInterpress): fixed scaling, Print: added parameter doNotScale.
