Mainly for Ralf ...

https://github.com/fricas/fricas/blob/master/src/doc/htex/ug07.htex#L154
REPLACE:
\spadgraph{draw(sin(tan(x)) - tan(sin(x)),x = 10..16)}
BY:
\spadgraph{draw(sin(tan(x)) - tan(sin(x)),x = 10..16,title=="A title here")}
MOTIVATION:
A title was announced the line before.

---------------------------------------
https://github.com/fricas/fricas/blob/master/src/doc/htex/ug07.htex#L222
REPLACE:
\psXtc{
The title may be an arbitrary string and is an
optional argument to the \spadfun{draw} command.
}{
\spadgraph{draw(curve(cos(t), sin(t)), t = 0..2*\%pi)}
}{
BY:
\psXtc{
Note that \Language{} provides a default title based on
the first function specified in \spadfun{curve}.
The title may be an arbitrary string and is an
optional argument to the \spadfun{draw} command.
}{
\spadgraph{draw(curve(cos(t), sin(t)), t = 0..2*\%pi, title=="A title here" )}
}{

DELETE:
Also note that \Language{} provides a default title based on
the first function specified in \spadfun{curve}.

MOTIVATION:
Sentence anticipated where it is relevant.
A title was announced the line before the first patch.

----------------------------
https://github.com/fricas/fricas/blob/master/src/doc/htex/ug07.htex#L276

MOTIVATION:
In 276 -- 293 \spad{p(x,y)} is used instead of a mathematical polynomial p(x,y).
I would eliminate \spad and use the command appropriate for maths.


In 296--310, The mathematical notation p(x,y) of a polynomial expression
is misleading in a command reference, and leads to think to a function p is needed.
I suggest to replace p(x,y) by p, and explain that it is an expression
of type Polynomial with variables x,y.

TODO:
Patch draw to show units when unit=... is given

MOTIVATION:
unit=-=... is used but nothing is shown in the image.

https://github.com/fricas/fricas/blob/master/src/doc/htex/ug07.htex#L400

REPLACE:
Option {\tt clip} with a range sets point clipping of a graph within the
BY:
Option {\tt clip} with a range shows only points within the

MOTIVATION: 'to set point clipping' seems quite technical, plain words are
better.

REPLACE:
++ Description: TwoDimensionalGraph creates virtual two dimensional graphs
BY:
++ Description: GraphImage creates virtual two dimensional graphs
MOTIVATION:
IIUC TwoDimensionalGraph does not exist (old name of GraphImage?)
