TODO: User interface to build new themes besides HBIDE defined ones.
If you have, furinish the themes to be included as HBIDE's
default themes, under follwoing heads:
* Compiler Directives - #include...
* Harbour Keywords - FUNCTION, DOCASE, ...
* Operators - :=, .or., ...
* Parenthesis and braces - (), {}, ...
* Functions in general - DBCreate(), ...
* Strings - "This is text", 'and this also'
* Comments - // Comment, /* Useful Routine */, ..
* Numeric constants - 123, 212.33,...
* Background color
The attributes will be ( in the order shown below )
aRGB = { 127,213,123 }
lItalic = .T. | .F.
lBold = .T. | .F.
lUnderline = = .T. | .F.
There are few more exotic attributes but for later...
