ImagerPress is a client interface for creating a kind of Imager context that will write Press files. The Press files created are in the subset that is acceptable to Spruce, the program that drives Dover printers.

An ImagerPress context maintains a set of Imager variables, so the client may inquire about current position, etc. Although you should not ordinarily care, the device coordinate system is in units of micas (100,000 micas = 1 meter), with the origin in the lower left-hand corner of the page. The initial coodinate system is, of course, in meters.

Only text and page-aligned rectangles are supported to a reasonable extent. Unsupported imaging operations will generate an informational signal, and try to muddle on.
