When importing DXF files using the C++ importer, TEXT and MTEXT entities
had incorrect heights. For example:
- text with height 100mm in the DXF file was imported as 35.28mm in FC.
The scaling factor was consistent to be 0.3528.
The issue was that we were applying a point-to-millimeter conversion to
the text height , but that seems to be incorrect since according to DXF
spec, TEXT and MTEXT entity heights are always specified in drawing
units, not in points, so just remove that code.
