This has been superseded by GDExtension so this code is no longer useful
nor usable.
There's still some GDNative-related stuff in platform export code which
needs to be adapted for GDExtension (e.g. to include GDExtension libraries
in exports).
Due to the port to Vulkan and complete redesign of the rendering backend,
the `drivers/gles3` code is no longer usable in this state and is not
planned to be ported to the new architecture.
The GLES2 backend is kept (while still disabled and non-working) as it
will eventually be ported to serve as the low-end renderer for Godot 4.0.
Some GLES3 features might be selectively ported to the updated GLES2
backend if there's a need for them, and extensions we can use for that.
So long, OpenGL driver bugs!
This should eventually be rewritten to properly test IO features,
but this would be part of a bigger work on adding a proper testing
framework for Godot features.
Fixes#2454.
Works both for the editor and games.
Projects can still use "debug/settings/stdout/print_fps" to enable it
permanently. The --print-fps option takes precedence (so works even if
the project setting is disabled). That setting is also no longer redefined
on the fly based on the verbose flag, that was a mess.
