GLES2 is not designed to be a drop-in replacement for the GLES3 backend,
so the fallback mode has to be used knowingly. It *can* make sense for
simple projects which make sure to handle the differences between both
rendering backends, but most users should stick to one supported backend.
By making it opt-in, we can now use this parameter to define whether to
export ETC textures to Android and iOS when using GLES3 + Fallback.
When using GLES3 without Fallback on Android, set the proper min GLES
version in the AndroidManifest.
Also made the option boolean and renamed it for clarity and to avoid
conflict with the previous String option (which would always evaluate as
"true" otherwise).
Fixes#26569.
It has a big impact on 2D and text rendering performance (cf. #24466)
so the solution seems worse than the bug it aims to work around.
It's now opt-in via "rendering/quality/2d/gles2_use_nvidia_rect_flicker_workaround"
for those who need it and have a simple enough game for the performance
drop not to be an issue.
Fixes#24466.
Previously, an error message would get printed to the console, but this
is problematic in e.g. Windows where a console is not displayed. In the
case of a missing .pck file, the binary would just silently fail. Now,
it shows an alert.
Fixes#21994.
Fixes the following Clang 7 warnings:

Image::load is now issuing warnings (since ef50957) to prevent users
from using it to load images at runtime which would be included in
their exported game.
So we now use ImageLoader explicitly instead for the custom-handled
cases in Main.
Fixes#21072, supersedes #22321.
Note, it will only used by the Editor, not when running the game.
This allows package maintainer to compile Godot to use system installed
certificates when accessing the AssetLib.
This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.
Previous fix in e8e06b2 worked in most cases but not if you run e.g.
'godot -', where the '-' argument would mean that 'project_manager'
is false and yet that's what will be opened eventually.
This adds a static is_viable() method to all rasterizers which has to be
called before initializing the rasterizer. This allows us to check what
rasterizer to use in OS::initialize together with the GL context
initialization.
This commit also adds a new project setting
"rendering/quality/driver/driver_fallback" which allows the creator of a
project to specify whether or not fallback to GLES2 is allowed. This
setting is ignored for the editor so the editor will always open even if
the project itself cannot run. This will hopefully reduce confusion for
users downloading projects from the internet.
We also no longer crash when GLES3 is not functioning on a platform.
This fixes#15324
-Project/Editor settings now show tooltips properly
-Settings thar require restart now will show a restart warning
-Video driver is now visible all the time, can be changed easily
-Added function to request current video driver
