* NxConsole needs to remember every character written to the console so
* that it can redraw the window. This setting determines the size of some
* internal memory allocations used to hold the character data. Default: 128.
* CONFIG_NXCONSOLE_FONTCACHE
* If this setting is defined, then caching of fonts will be supported by
* NxConsole. Each font must be rendered from the tiny font storage format
* to the full display size and pixel depth. If this setting is defined, then
* the more recently used font glyphs will be retained in a cache of size
* CONFIG_NXCONSOLE_CACHESIZE. Default: No font caching.
* CONFIG_NXCONSOLE_CACHESIZE
* If CONFIG_NXCONSOLE_FONTCACHE, then this setting will control the size
* of the font cache (in number of glyphs). Default: 16.
* NxConsole supports caching of rendered fonts. This font caching is required
* for two reasons: (1) First, it improves text performance, but more
* importantly (2) it preserves the font memory. Since the NX server runs on
* a separate server thread, it requires that the rendered font memory persist
* until the server has a chance to render the font. (NOTE: There is still
* inherently a race condition in this!). Unfortunately, the font cache would
* be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting
* will control the size of the font cache (in number of glyphs). Only that
* number of the most recently used glyphs will be retained. Default: 16.
* CONFIG_NXCONSOLE_LINESEPARATION
* This the space (in rows) between each row of test. Default: 0
* CONFIG_NXCONSOLE_NOWRAP
