[LazFreeType] effect on the accuracy outlines of the TFreeTypeFont.SizeInPoints?

[zamtmn]

I noticed that if you do not change after loading font size, then for some fonts contour accuracy drops sharply and the letters are dancing. If you set the height of a large number, then everything is fine. Apparently affects the internal precision of points. How to determine the optimal height of the font?

I made ​​a small example for сyrillic truetype font OpenGostTypeB-Regular.ttf. Sources with font and animated gif with problem are included.

Interesting project. Unfortunately it crashes in Lazarus 3.8.

It not project, it experiments before write ttf render for zcad(https://forum.lazarus.freepascal.org/index.php/topic,16665.0.html https://github.com/zamtmn/zcad)

The result was this https://imgur.com/a/eY7OkXR

Now there is very bad code there - traces of experiments and errors, I did not plan to make it a separate part, but if there is interest, I can comb it and separate it.

I think it could be useful for many people to have a TTF renderer. It could be used to make a font converter, editor, use custom fonts in games and more.
