#211 Broken colour/group handling in LO and TexMaths >0.52

[pglpm]

I notice that with LO v26.2.5.2 (X86_64) and any version of TexMaths >0.52, LaTeX saved as 'svg' cannot be entered as a group, in order for instance to change colours (or do other transformations to the individual letters).

This functionality instead works with TexMaths v0.52. I don't know when the regression happened; this is similar to #168.

Thank you again for this invaluable extension!

Yes, since TexMaths 0.52.1 SVG equations are no more converted to curves. This was used for compatibility with MS Office. But this had issues with imperfect equation rendering in some LaTeX packages (chemfig, tikz, pstricks for example) that are often used by TexMaths users.

Now in recent LibreOffice versions, this trick (conversion to curves) is not needed anymore. So I removed it. But it has the side effect that it is not possible to change the equation color with the mouse in LO.

In Draw or Impress, you can select the SVG equation, right click on it and select 'To curve' and after that you'll be able to change the color with the mouse. I don't think it's possible in Writer but I'm not sure.

Another way is to define custom colors in your TexMaths preamble, like this:

\definecolor{mycolor}{RGB}{0, 132, 180}

Then in the TexMaths Equation dialog you can type:

\color{mycolor} x + y = z

and your equation will have the selected color.
