[fpc-pascal] Resource compilation

[Giulio Bernardi]

Hi everybody, I'm just chiming in after quite some years.
Just two notes:

* For lazarus, it shouldn't need to use a real resource compiler for standard
things like icons, manifests etc: see programs res6 and res7 at
https://www.freepascal.org/docs-html/fclres/basic%20usage.html

* For the "real" resource compiler, regarding Martok's comment:

Actually, fcl-res was designed as a library to be used by a resource compiler,
and I don't think you need to implement new classes at all: once you have
written a parser for .rc files you just have to read the files referred from the
.rc file (icons, raw data etc), create the right kind of resource and add to the
output TResources. IIRC all the standard resource types were already
implemented, so once you write a parser that handles .rc files you should be done.
