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.
We were passing raw Gfx::Bitmap objects into the various image decoders
instead of encoded image data. This made all of them fail, but the test
expectations were set up in a way that aligned with this outcome.
With this patch, we now test the codecs for real. Except ICO, since we
don't have an ICO file handy. That's a FIXME.
With the goal of centralizing all tests in the system, this is a
first step to establish a Tests sub-tree. It will contain all of
the unit tests and test harnesses for the various components in the
system.
