GtkGLExtSharp
Pick up from old version and I have replaced to new one for GtkSharp 2.12.x
Change and Update:
Removed ATI related method ( No longer support for AMDGPU ) Replaced 2 libs into one lib GdkGL and GtkGL into GtkGLExit Added config dllmap with libgtkglext and libgdkglext
Note for Windows 10
If you use Windows 10 then you need find and download from GtkGLExt github or Sourceforce.net
Sorry I don't care for Windows 10.
It works finer under Ubuntu 18.04 with Latest Mono Runtime 6.x and Dotnet 3 / 5 too.
