Research direction

Start by comparing the font-cache handling in examples/nx with the improved handling in examples/nxtext. Read the common font-cache interfaces defined in nxfonts.h and check how the NXTERM font cache is exposed. Done means both examples use the common cache and fonts are removed correctly when the cache is full.

Written by the indexing model from the issue text.

Description

Type: Migrated TODO

  Description: The font caching logic in examples/nx is incomplete.  Fonts are
               added to the cache, but never removed.  When the cache is full
               it stops rendering.  This is not a problem for the examples/nx
               code because it uses so few fonts, but if the logic were
               leveraged for more general purposes, it would be a problem.

               Update: see examples/nxtext for some improved font cache handling.
               Update: The NXTERM font cache has been generalized and is now
               offered as the standard, common font cache for all applications.
               both the nx and nxtext examples should be modified to use this
               common font cache.  See interfaces defined in nxfonts.h.
  Status:      Open
  Priority:    Low.  This is not really a problem because examples/nx works
               fine with its bogus font caching.
