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.
Fuzzless and sweeter than peaches (Suzanne Williams)
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.

Geometry
Does what FreeTesselation supposedly did once upon a time.
PROC [tile: REF Tile, data: REF]
This version is much slower than PrintTile.  It uses 4 additional operations and 12 additional bytes.  This buys that all rectangles get aligned to pixels.  This makes that all wires in schematics are printed with the same width.
PROC [tile: REF Tile, data: REF]
Prints a band.  If there is only one band and no clipping is necessary, setting clip to false will make it faster.

Note that merging works correctly because of the use of the colour table.

The procedure for rectangles is called through the recursion step.
Interpress
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.
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.
Creates the interpress master.
Called back by the Interpress machinery.
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.
y0 _ IF ratioH < ratioW THEN 0.0 ELSE field.h - window.h * ratioW;
Rectangles:
Magic numbers: Assume 14 MB of memory may be used.  Each tile requires 16 words of storage (14 words for the tile and 2 words Cedar overhead), hence 106 tiles can be stored.  In the current worst case, a die is 10 mm wide.  If a gate can be 2 mm long, in the worst case there is a rectangle each mm.  In the average there are as many space tiles as there are colored tiles.
The intersection of the current band with the clipping window is performed by PrintBand.  The field state.cdClip is assigned earlier.
Produce bands from high to low y-coordinate values in order to avoid paging in succeeding software.
The first bands are not typical, because they are not dense.
Text:
The stroke joint must be round, because a ChipNDale staightline segment [a, b] is made out of a spline [a, b, a'], where d (a, a') < e.
Does it at background priority.
Produce preamble.
It is not possible to declare all colours in the preamble, because the size of the Interpress frame is 50 entries (this is defined in the Standard).
Create a table of the fonts and them in the preamble.
Produce the page.  All coordinates will be in millimetres.
Close.
The keep of Interpress masters is 1.  Unfortunately PeachPrint does not lock a file between the time it posts a request and the request is served.  This can not only cause the files to get lost, but it may even hang some print servers.  The solution implemented here, i.e., changing the keep to 3, it to be considered as a mild temporary hack until a proper solution becomes available in 3 weeks from the time these lines are written.
Calling FS.SetKeep will have the side effect of deleting files that are obsolete relative to the new keep, even when the keep is not changed.
Same as CDOps.DrawDesign, but visits only the selected objects.

Must be fast as a bullet
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).

There is no facility offered by ChipNDale to visit only a cell without recursing to its subcells, so here is a homebrew hack.
[inst: Instance, pos: Position, orient: Orientation, pr: REF DrawInformation]
The map is global, because fonts rarely change across designs.
DrawDesign is an overkill, which easily takes 20 minutes on the CrossRAM.  There is no facility offered by ChipNDale to visit only a cell without recursing to its subcells, so here is a homebrew hack.
Translates from strike to spline fonts.
Construct the old style name:
Find the size and face from the old style name:
Compute the size (assume: there always is a size):
Determine the face:
CdPos: PROC [v: Imager.VEC] RETURNS [CD.Position] ~ BEGIN
RETURN [[Round[v.x], Round[v.y]]]
END;	-- CdPos
Assume that LayerColour had previously been called.
Writes a message in the ChipNDale terminal viewer and in the Message Window at the top of the LF screen and makes it blink.
Printing
This is a mess.  The religion asks me to propagate the error I get from PeachPrint to my client.  However, PeachPrint just sits there until all printing is done or aborts locking up ChipNDale.  Therefore, until PeachPrint is not fixed and forks off a process by its own, I do it myself and swallow that bloody event.
If the image is in portrait format and the printer uses roll paper, the rectangle usedField from DoInterpress can be specified as a sizeHint to increase the scale so a to use the full roll width.
Note: the origin in PDParams refers to the field, not to the medium.
Should be in Cedar.
Roll paper.
Roll paper.
Use the following three statements to obtain very fast colors:
Or use the following statement to obtain quality colors (rotated screens):
deviceParameters.ppd _ 2.0
Roll paper.
Roll paper.
Cut paper.
Implementation notice: because of some possible arcane bug in the compiler, if the scales in x and y would have been first defined either as contants or variables, the compiler would set them to the value 0.0.  Therefore you should not change the next line.
The adjustement of the field to the left end of the printer head has to be scaled, because the field is included in the coordinates in the Interpress master.
The keep of PD files is 1.  Unfortunately PeachPrint does not lock a file between the time it posts a request and the request is served.  This can not only cause the files to get lost, but it may even hang some print servers.  The solution implemented here, i.e., changing the keep to 3, it to be considered as a mild temporary hack until a proper solution becomes available in 3 weeks from the time these lines are written.
Calling FS.SetKeep will have the side effect of deleting files that are obsolete relative to the new keep, even when the keep is not changed.
SIGNAL communicationsFailure
Produces (if necessary) a PD file from an Interpress master and ships it to the printer.  Valid printer keys are $NVersatec, $NColorVersatec, $NPeachExpand, $NBw400, $NColor400, $NPlateMaker, $NRaven300.  May return signals invalidPrinter.
If the image is in portrait format and the printer uses roll paper, the rectangle usedField from DoInterpress can be specified as a sizeHint to increase the scale so a to use the full roll width.
Statistics
Lists the statistics on the colour table.
We initialize only the area so as to cache colour blendings across sessions.
Although the INT returned BasicTime.Period is the same as GMT and might hence be loopholed to use IO.time from Conversions, the latter uses BasicTime.Unpack which allows only values that give a valid date.

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.
