Default [Q] Can you explain these 2 lines?

Hello!

Can you explain me a bit what these 2 lines do? know it's something with webview but I would like to understand what does
TARGET_FORCE_CPU_UPLOAD and ENABLE_WEBGL do.
Quote:
# Web Rendering
TARGET_FORCE_CPU_UPLOAD := true
ENABLE_WEBGL := true
If I don't want to use classic webview, do I have to comment out both of them?
