this is to not force _some_ sdl2 type usage onto applications, thus
forcing them to also include sdl2 as a dependency themselves.
that being said, this is still pretty gross feeling to me and i wish
there was a better solution.
i've not added all possible sdl2 event equivalents. only the ones that
i am currently interested in and use. i'll add more as is needed. likely
the joystick / controller events will be added in the very near future.
0.35.2 is the latest version available via cargo right now, and that
version has some issues building for me that have been resolved in
subsequent commit(s). for some reason the maintainers have not pushed
a new version of sdl2 to cargo for quite some time despite numerous
fixes and updates being available ...? bah!
also the current sdl2 `features` set will probably only work for linux
builds. i will try to work out windows + mac build issues shortly
due to encountering some compile errors on a fresh system which pulled
down the newest minor versions of both. these two libraries do not seem
to follow "good" semantic versioning ... ? ugh. will try to work out
the compiler issues with the latest versions of these later ...
