We now truncate the font name as it goes out to GDI APIs, in console API
servicing, and in the propsheet.
I attempted to defer truncating the font to as far up the stack as
possible, so as to make FontInfo usable for the broadest set of cases.
There were a couple questions that came up: I know that `Settings` gets
memset (memsat?) by the registry deserializer, and perhaps that's
another place for us to tackle. Right now, this pull request enables
fonts whose names are >= 32 characters _in Windows Terminal only_, but
the underpinnings are there for conhost as well. We'd need to explicitly
break at the API, or perhaps return a failure or log something to
telemetry.
* Should we log truncation at the API boundary to telemetry?
-> Later; followup filed (#3123)
* Should we fix Settings here, or later?
-> Later; followup filed (#3123)
* `TrueTypeFontList` is built out of things in winconp, the private
console header. Concern about interop structures.
-> Not used for interop, followup filed to clean it up (#3123)
* Is `unsigned int` right for codepage? For width?
-> Yes: codepage became UINT (from WORD) when we moved from Win16 to
Win32
This commit also includes a workaround for #3170. Growing
CONSOLE_INFORMATION made us lose the struct layout lottery during
release builds, and this was an expedient fix.
Closes#602.
Related to #3123.
