Implement btIDebugDraw for Magnum

[Squareys]

Hi @mosra !

As promised via gitter, here is the PR for the bullet physics visualization ( #11 ).

There is one // TODO in draw3dText(...), you might want to look at how to specify/format it instead. I could also adapt the bullet example and whilst I'm at it remove the Shapes dependecy from it (since it will be deprecated) once you merged this.

Regards, Squareys.

Uh... I guess it's not set up for magnum-integration yet?

[mosra]

No. If you remember, that's STILL because of this: https://github.com/travis-ci/apt-package-whitelist/issues/1190

I'm getting angry just seeing that issue.

The Bullet integration lib is built for OSX, but there I don't have the code coverage enabled. Maybe I should give up on waiting and build Bullet from source in this case.. :/

[Squareys]

No. If you remember, that's STILL

Right, forgot about it, it's been a year since.

Any other comments on the PR? For once it is not WIP, was simple enough ;) (Not pushing, would be great to have this upstream, though.)

[mosra]

Review done :)

The OSX build fails because of missing Shaders dependency. Can you update the CI files accordingly?

Regarding the text rendering -- yes, as you suggest, i think the better option long-term would be to use the "debug text" functionality once it's in. The TODO is fine like this. Or, maybe, put it in a Doxygen @todo block.

Until then, if you feel like doing it (just a suggestion!), even just copypasting the guts of the Text example and having the constructor take an optional Text::AbstractFont* font pointer with an opened font -- i.e. assert on it like this:

CORRADE_INTERNAL_ASSERT(!font || font->isOpened());

If the user won't supply the parameter (the default), it will not render any text. If the user provides the text, it will render it.

Eh, scratch that, now realized that this will be kinda hard to do with this "immediate" approach of the interface, as there is no flushText() or anything similar. Would need to think about it a bit more.

Cherry-picked as f8eb01d66d44569b4ffb8000cc51922dbb28a43e, 28eb3c7d0c02d7d79fa7f2d5d1d5c03ff93bb96c and de3b54e3f10662d1b57db73fafa6e2f2ae7bf33b. On Linux the test failed the same way as on OSX, so I added an explicit cast to UnsignedInt before casting to void* to avoid sign extension.

What's with https://github.com/mosra/magnum-integration/pull/21/commits/a08be624805ffe37df27f39f0ea6d114c06e4ce5? (Ah, I see that was also squashed into one of the other commits)

[mosra]

Into both, actually :)

I'm leaving the cleanup commits only in case they are not by the same author (so people can see the changes others made to their code).
