R devel - May 2024 - FR: Customize background colour of row and column headers for the View output

This seems like something that should be fairly easily doable.  Why 
don't you work out a patch?

Some decisions to make:

- What colours are we talking about?  Would you want the labels to have 
their colour set independent of the dialog colours?  If so, would you 
also want to configure the dialog colours?

- What names should be used for the colours?

- Where should all of these definitions be documented?

If you don't feel comfortable with the coding, perhaps you could answer 
these questions, and someone else may code it for you.  I won't (I no 
longer have easy access to Windows), but I could help with the design.

About the decisions:

Actually, the same way dataedittext modifies the text colour not only
of data, but also of row and column names, and dataedituser modifies
the colour of all the borders, I think dataeditbg should modify the
background of all the window, at least that "inside" those
borders. Otherwise, any other option for the background colour on row
and column headers would allow the same set of colours and with the
same names, which are those commented in Rconsole:

## Colours for console and pager(s)
# (see rwxxxx/etc/rgb.txt for the known colours).

Regarding the code, looking to the Windows data editor [1], and taking
into account what you and lastly Ivan told previously

    This is entirely correct: the dialog uses the colour returned by
    dialog_bg(), which is GetSysColor(COLOR_BTNFACE).

(maybe a naive question from who does not know the code), could not be
used `guiColors[dataeditbg]` instead of `dialog_bg()` in the unique
place this is present?. So, instead of

    bbg = dialog_bg()

it would appear

    bbg = guiColors[dataeditbg];


Thanks!
Iago
