f/selection improvements

ekcoh commented 3 years ago

Primarily additions to management of selections in resemblence with proposal in https://github.com/Nelarius/imnodes/issues/106:

Added API to programatically select nodes and links.
Added API to programatically clear selection of specified node/link.
Added API to check whether a node or link with specific id is currently selected.
Fixed implicit conversions between float-double by using float-specific math functions instead of double functions when origin is float type. This eliminates warnings on higher warning levels and eliminates casts/truncation. (bonus)
Casting result of sscanf to void to avoid warnings on higher warning levels. This also signals that code is not checking for errors.

Hi @ekcoh and thanks for the contribution! I think the addition makes a lot of sense.

Out of curiousity, which warning levels are you using? I recompiled imnodes with -Wall -Wextra but I wasn't able to trigger any warnings.

@Nelarius Sorry for the late response, but from what I recall I used MS VC 2019 Windows target with CMake and -WAll
