nTropy2D.

(The number of puns we can do with Crash Bandicoot bosses and nSpire are just fantastic.)

I third the nTropy2D name.
Also lol @ocd aeTIos.

I find nTropy2D very ugly (and thermodynamics-ish), so I'll go with n2DLib, as does the results of the poll say.

New features are regularly added, especially for geometric drawing. Since the purpose of this library is to allow us to make the fastest possible functions, we wanted to ask you if you had any suggestions, if you wanted us to add some features that could be useful to everyone or especially to yourself, so that this lib can be as practical, diverse and wide as possible.
Some radical changes have also been made with the gestion of the buffers, but the functions are still the same and there aren't any changes user side.
But I let matref be more precise, since he's the one who modified the functions. 

Well no, what do you want them to say ?

Anyway, you should instead say that you added geometry functions, like lines, wireframe polygons and filled circles and ellipses

So by the time of the last update we fixed many things making the lib faster (for example always allocating a second buffer for the screen so it can be accessed faster than this latter), and I just added a drawString() function
By the way, I also wrote an extensive documentation.
Code is still at the same place : https://github.com/n2DLib/n2DLib

Attached is screenshot of the example program running

Cool to hear ! Updating now.
I'm probably gonna add the lib as a submodule.
