We're going to eventually include this class in all Application classes
(need that in order to inherit a to-be-created Configuration class) and
the <string> and <vector> would be just too much. This change caused
magnum-gl-info.wasm (WebGL 2 build) to go down from 247 to 245 kB. Not
much, but that's I guess because there's still a lot other vectors of
strings elsewhere.
There's a lot more places to clean up, will do those in separate
commits. This change is the most atomic I could do, and it introduces a
breaking change to all APIs that returned a std::vector or a
std::string. Fortunately (or as I hope) those weren't used that much, so
it shouldn't cause build breakages for that many people.
Quite a lot of the optimization ideas is borrowed from the new Vk
library -- such as "interning" the driver workaround strings to avoid
allocating their copies.
Good thing I checked this -- based on WebGL I was under assumption that
all GPUs have it just 256, but that was really just WebGL limitation.
Also ugh why this query wasn't there since the 90's?
If building with deprecated features enabled, the buildsystem checks if
the option is still set and is inconsistent with what Corrade reports
and reports a deprecation warning. For backwards compatibility the
MAGNUM_BUILD_MULTITHREADED CMake variable and preprocessor macro are
still provided as well.
A bunch of extensions formerly in AEP are now part of ES 3.2, which
means they were reordered in the extension lists. While at it, also
added corresponding new GL and WebGL extensions and fixed a few wrongly
categorized extensions in WebGL.
Detected in WindowlessWglApplication, added it to both Sdl2Application
and WindowlessWglApplication. Renamed the workaround to reflect that it
is for all three major vendors.
