TODO

gwbuild:
- new entry "prefix" (internally translate to option_prefix stuff like in AqFinance)


GUI dialogs:
- implement "keyPressed" and "keyReleased" events in GTK3 and QT5 frontends
- implement "frame*" widget flags in GTK3 and QT5 frontends

typemaker2:
 - add a field annotoations (e.g. "personal data")

logger:
 - finer granularity for loglevels
   - introduce subdomains
     - gwenhywfar/syncio
     - gwenhywfar/http
     - gwenhywfar/gui
     - etc
   - GWEN_Logger_CreateSubDomains(maindomain, "syncio,http,gui,db,xml,crypt", logLevel)
   - GWEN_Logger_SetupSubDomains(maindomain, "syncio=notice,http=debug,gui=info", defaultLogLevel)
   - in source files, e.g. syncio_http:
     #ifdef   GWEN_LOGDOMAIN
     # undef  GWEN_LOGDOMAIN
     # define GWEN_LOGDOMAIN "gwenhywfar/http"
     #endif

sio:
 - ssl_cert_descr -> typemaker2

tm2:
  - inline loc="struct" -> insert fields into the struct definition

  - inline loc="constructor": -> insert code into constructor
  - inline loc="destructor": -> insert code into constructor
  -> or maybe: make the field definition also a part of the tm2 mechanisms
     already in place (i.e. defined in tm2 files?)


xml:
  - add argument to file reader/writer code which contains the target
    encoding

Callgraphs

- Generate callgraphs:
  make CC=/usr/gccgraph/bin/gcc
  C  : genfull
  C++: genfull -g cppdepn
- Show callgraph for s specific function:
  gengraph -f FUNCTION_NAME -o OUTFILENAME --output-type=png
