TODO and known issues
=====================
Lua generic terminal
* support color palettes (low priority, not really needed for TikZ?)
* support enhanced text mode (low priority, not really needed for TikZ)
* sort out what needs to be built + included as part of preparing a
distribution package
TikZ backend
* automatic detection of font sizes (via LaTeX test call?! very low
priority. It works with the gnuplottex package and the charsize option,
see style file for an example)
* setting the background color within a gnuplot (gnuplottex) environment
does not work if the tikzpicture environment is used of this scope:
\begin{tikzpicture}[gnuplot]
\begin{gnuplot}[...]
\end{gnuplot}
\end{tikzpicture}
As a workaround the background color can also be set manually right after
\begin{tikzpicture}[gnuplot] using the \gpsetbgcolor{R,G,B} command.
* there is an incompatibility/bug of the preview package and TikZ that leads
to erroneous files on dvi and postscript output using the terminal's
standalone mode. PDF output works flawlessly.
* pattern fills are not supported by XeTeX
