A transitional variant, since the exe a player runs may not have the new
renderers. The old renderers stay in the list and the old keys are still written
next to the new ones. A new exe without Vulkan starts OpenGL by itself, an old one
reads the word as its legacy renderer, and both pass over the keys they do not know.
Taken from Hirek193's branch:
- the new keys as rows of a section of their own, with their texts
- their values on the graphics levels, in steps over the six levels here, with
High as what the simulator does with nothing set
- Vulkan 1.4 in the list of renderers, and its own keys marked as idle without it
- gfx.buffer.percent next to the old buffer keys, read before them
- gfx.antialiasing saved below multisampling, for the later line to count
Keys checked against feat/gl46-migration of the simulator.
Left out, as this branch has its own or does not need them: the rewritten settings
page and its five levels, GraphicsRules, the DLSS library check, eu07.ini import and
export, and the removal of the old renderers.
A failed write leaves the old file in place. Settings that could not be read
are not saved over. UI exceptions reach the log. Started from a shortcut set
up elsewhere, the starter moves to its own folder when only that one holds a
game.
