This shouldn't normally happen as conforming drivers are required to
support that texture format, but the software driver that we
accidentally choose on Poco C40 (see issue #16391) doesn't.
That we choose that driver will be fixed separately. This fix on its own
at least lets the user comfortably navigate to settings and switch to
OpenGL.
* Wrap the display globals in a struct
Makes it easier to search/replace these, for future refactorings.
* Some renaming
* Qt buildfix, also fix the Qt build on Mac (got broken with battery changes)
* Attempt at buildfixing ios
* UWP buildfix
And thus change of depth buffer scale/offset.
Previously, old depth buffers with values that now are out of range
could stick around, causing #16941. This clears them to the expected 0
value, which helps Outrun. Ideally we should convert depth buffers to
the new format, but if we can get away without that, that's also nice.
This is enough for #16941.
We have to assume that ForceLowerResolutionForEffects has been set for
good reason - in this case, the effect probably can't safely function
without it.
Fixes#11100 once again.
