[erlang-questions] color customization

The debugger uses wxStyledTextCtrl which seems to override window manager
settings for background, it is easy to override the hard coded values but
different from other windows which is why it probably does not work by
default.

Not as trivial to fix so that it works for all (themes/OSes), tough.

Example:
diff --git a/lib/debugger/src/dbg_wx_code.erl
b/lib/debugger/src/dbg_wx_code.erl
index a0e6c94..cd85fe7 100644
--- a/lib/debugger/src/dbg_wx_code.erl
+++ b/lib/debugger/src/dbg_wx_code.erl
@@ -88,10 +88,12 @@ code_area(Parent) ->
        {?wxSTC_ERLANG_MODULES, {64,102,244}},
        {?wxSTC_ERLANG_MODULES_ATT, {64,102,244}}
       ],
+    ?stc:styleSetBackground(Ed, ?wxSTC_STYLE_DEFAULT, {127,127,127}),

     SetStyle = fun({Style, Color}) ->
        ?stc:styleSetFont(Ed, Style, FixedFont),
-       ?stc:styleSetForeground(Ed, Style, Color)
+       ?stc:styleSetForeground(Ed, Style, Color),
+       ?stc:styleSetBackground(Ed, Style, {127,127,127})
        end,
     [SetStyle(Style) || Style <- Styles],
     ?stc:setKeyWords(Ed, 0, keyWords()),

I guess most of the other windows work OK then, since tables in observer
are hardcoded in observer_defs.hrl,  see BG_EVEN/ODD defines.
