DefaultRVFPixelsPerInch Typed Constant
DefaultRVFPixelsPerInch: Integer = 0;
This value is used as PPI (pixels per inch) for RVF files saved by TRichView versions prior to 17.6.
Since version 17.6, TRichView saves PPI value in RVF file. This value is used to scale controls from RVF's PPI to the actual PPI. For older RVF, the value of this constant is used.
0 is a special value meaning no scaling.
