Materials can't compile on Windows

[nabeelsherazi]

Hello!

I'm new to this project and just trying to get it to build for the first time on Windows 10. I'm using a clean Anaconda environment with all dependencies shown as listed in requirements.txt. I haven't encountered the DLL load issue that is mentioned in the README for Anaconda.

Instead, when I run main.py, I find that every material is failing to compile. Each one provides this error:

 (Material.py:200)

ERROR: 0:1598: 'texture' : function is not known

This error happens over and over again until all materials are done loading. Then, presumably because none of these materials load, there is this traceback (some lines cut for brevity):

Traceback (most recent call last):
  File "main.py", line 104, in <module>
    next_open_project_filename = run(editor, project_filename)
...
  File "C:\...\PyEngine3D\PyEngine3D\Render\Terrain.py", line 112, in render_terrain
    material_instance.use_program()
AttributeError: 'NoneType' object has no attribute 'use_program'

I'll dig in further to see if I may be able to find something more, but I'm very new to 3D rendering and so my ability to help may be limited.
