    Description

      FontMetrics.zip
      This is a test program I made.

      DejaVuSerif.zip
      This file contains "DejaVu Serif" font.

      I tested the FontMetrics program on "DejaVu Serif" font. The screenshots are:
      FontMetrics-w2k3.png
      FontMetrics-w10.png
      FontMetrics-r75977.png

      I can say from observation, that ReactOS has reported a wrong height value at GetTextExtentPoint32 function.
