Everywhere: Add sv suffix to strings relying on StringView(char const) Each of these strings would previously rely on StringView's char const constructor overload, which would call __builtin_strlen on the string. Since we now have operator ""sv, we can replace these with much simpler versions. This opens the door to being able to remove StringView(char const*). No functional changes. 2022-07-11 17:32:29 +00:00			`static constexpr StringView image_type = "PPM"sv;`

LibGfx: Use common class template for PBM/PGM/PPM image loaders PBM, PGM, and PPM image loaders are mostly common. The only difference is how the data is read and the associated magic numbers. The magic numbers are already made common using the loading contexts. Now make the implementations common via a class template which accepts the context to disambiguate. 2022-03-13 11:58:58 -06:00			`using PPMImageDecoderPlugin = PortableImageDecoderPlugin<PPMLoadingContext>;`
