/* Currently, we allow the user to select the size of the font used, and
the family/foundry. Within that, the document author specifies
a size from 1-7, a face (normal, bold, italic, bold-italic) and whether
the font is fixed or variable width. Meaning 7*4*2 = 56 possible
fonts (but we load lazily).

* fe_loadUnicodePseudoFonts
*
* At this time, Sept. 1996, Unicode fonts are not

* we convert the Unicode string to a series substrings each
* of which is converted in a locally displayable encoding.
* We then display (size) each substring using a standard
* X font from a this Unicode Pseudo font.
*
* A Unicode Pseudo font is therefore an array of X fonts
* each of the given size/pitch/weight for this font with one
* one X font per encoding.
*
* In loading these Unicode Pseudo fonts we pretend to
* to have these Unicode fonts available and fill in the master
* font table. Actually checking for a X font for each
* for each size/pitch/weight/encoding would require loading
* a huge number of fonts.
*
* 11 sizes * 2 pitches * 2 weights * 35 encodings = 1540 fonts
*
* Because of the large number of fonts and the fact that asian
* fonts are large (1M per font) and the fact we might ask for
* scaling this loading time could be in the order of
* several minutes. During this font loading time the X server
* appears to freeze and this is quite distressing to the user.
*
* HENCE BECAUSE OF THE UNACCEPTABLE LOADING DELAYS
* WE JUST ASSUME THE UNICODE FONTS ARE AVAILABLE.
*
* Even when we begin using a Unicode Pseudo font we only
* load the X fonts for the encodings that have actually been
* seen. Just loading X fonts for all the encodings for a given
* size/pitch/weight requires a large number of X fonts.
*
* 11 sizes * 2 pitches * 2 weights = 44 X fonts
