DrawText3d method takes a fontSize argument which seems to be not working. How to change font size using this method?

I don't use SharpGL anymore. Offscreen rendering in C++ and texture transfer are bringing better performance results

bug: remove the non-functional 'fontSize' parameter from DrawText3D
69b5de5 
The fontsize parameter doesn't (and cannot) work. Instead, perform a
scale transformation before rendering the text.

Closes #148.

OK I've double checked - the font height is passed to the CreateFont function, but the underlying wglUseFontOutlines function doesn't actually care about the size of the font, it just creates the geometry. The only way to scale the font is by performing a scale transformation.

I've removed the parameter and updated the samples.
