[Devel] more on new error scheme

[Werner LEMBERG]

I'm still hesitating to implement my proposed scheme.

For applications, the following changes would be necessary:

  if ( error & 0xFF == FT_Err_... )
             ^^^^^^

Is this acceptable?  Which real programs actually use FreeType errors?
A better looking way is probably

  if ( FT_ERROR( error ) == FT_Err_Unknown_File_Format )
    ...

and similarly (ANDing with 0xFF00)

  if ( FT_MODULE( error ) == FT_Mod_Err_Cache )
    ...

to get the module in which the error has happened


Comments?
