Yes, but without a TCanvas scale factor or float type positions you can not use
it. So my conclusion is:
fractionals are needed in some rare cases, but supporting them requires a lot of
work. Coming back to the origin of the thread: Especially porting a Delphi
application should not need it, because the VCL does not support them. The LCL
carbon intf must be fixed, not the LCL.
