TDirect2DFont.GetHandle fontsize?

[pcoder 4]

By API docs, DWriteFactory.CreateTextFormat() expects device-independent pixels (DIP),
but the call seems to get physical pixels: MulDiv(Size, FPixelsPerInch, 72).  An issue or not?

Answering to myself: This is OK for (TDirect2DCanvas.RenderTarget.dpi = 96) only, ie (pixels = DIPs).
dpi 96 (regardless of screen dpi and font.dpi) allows clients to pass pixel coordinates to all Direct2D-functions which want DIPs.  
This is GDI-compatible, so clients must provide final pixel values (dependent on screen (or other) DPI).
