The first version of the PostScript language was released to the market in Reference manual. It is the enclosing program's responsibility to establish a suitable state just before the inserted EPS and restore the prior state afterward. At the time, the technology for including these hints in fonts was carefully guarded, and the hinted fonts were compressed and encrypted into what Adobe called a Type 1 Font also known as PostScript Type 1 FontPS1T1 or Adobe Type 1. One could create the path repeatedly for each one, alternatively one could define something like the following. On level 3 PostScript a sampled image can be used for clipping another sampled image. The language syntax uses reverse Polish notationwhich makes the order of operations unambiguous, but reading a program requires some practice, because one has to keep the layout of the stack in mind. When the file is reduced to a single procedure, try to replace it with inline code.

The frames are drawn in nupshowpage procedure. This led to numerous issues where the on-screen layout would not exactly match the printed output, due to differences in the implementation of these features. If the problem is not yet apparent try to make the smallest possible program that still has the problem by removing or commenting out pieces of code.
Merging the planes on vector level is much more difficult.
This question is asked almost every month on comp. Try to run the program on different interpeters.

Ghostscript home page is an alternative distribution site for Ghostscript and related programs. Almost all plotters shared a common command language, HPGLbut were of limited use for anything other than printing graphics. The drawing commands such as stroke and fill destroy the current path, the way around this is to use gsave that saves the current path so that it can be reinstated with grestore.
SourceForge is a primary Ghostscript distribution site.

You'll probably also need a layout engine like Pango to process the Unicode codepoints into series of glyph ids and precompute their position within the PostScript-rendered document where these will be encoded and decoded by the PostScript engine using the associated filter.
