comment code causing distorted picture for neutrinordp like black lines ...

...left of cmd windows.

I nailed it down to this peace of code what seems to have been introduced as workaround for freerdp but causing problems for neutrinordp-modul now using Microsoft MSTSC Client:

"workarounds for freerdp not using fOpRedundant in glyph.c::update_gdi_glyph_index"

It was introduced with this commit:
https://github.com/neutrinolabs/xrdp/commit/2aad1b2d5da9d7412092d8c76601fa9bca95685d

So this area needs attention. 

I don't know if commenting this section has any effect for freerdp now.
