- break it into four layers:
54-
: low level graphics (some of term.c)
55-
: plotting code, reading the setshow.h global variables

: parsing code - read a string, and parse and execute it

Ethan's list of ideas for development series 5.3
76+
================================================
77+
78+
Code cleanup
79+
------------
80+
- remove all the original axis_log/delog macros
81+
- other obsolete macros? HUGE? GPFAR? MSDOS remnants?
82+
- refactor VMS conditionals so that all the code is in vms.c
83+
- use libm Bessel functions j0, j1, y0, y1, jn, yn if present
84+
rather than the hard-coded ones in standard.c
85+
NB: the ones in standard.c claim accuracy to 1e-13
86+
the libm man page for j0 claims accuracy to 2e-16
87+
- Other libm functions?
88+
- matrix data should be stored as (double) not (float)
89+
- audit all FIXMEs, some must be out of date
90+
- further optimization of STORE_WITH_LOG_AND_UPDATE_RANGE
91+
to increase speed and reduce code size
92+
93+
Build system options
94+
--------------------
95+
- OSX autoconf
96+
- all-qt or all-cairo build targets
97+
- emscriptem build target
98+
99+
Terminals
100+
---------
101+
- canvas terminal overhaul (use browser's font support)
102+
- gnuplot enhanced text --> LeTeX conversion
103+
- possible updates for
104+
dxy aquaterm
105+
106+
Fitting
107+
-------
108+
- Patch #655 (Bastian Maerkisch) additional fit algorithms
109+
110+
Ideas for core extensions
111+
-------------------------

- 64-bit integer arithmetic
