OpenGL buffered backed is great!

Hi,

I have updated to latest commit, and found out opengl buffered backed is great! we have amost 100+ fps at full speed. Thanks for this great feature!

We use buffered backed now is because now it support GL2, so a name nanovg_gl3buf.h is not suitable for this backend, what about only nanovg_glbuf.h ?

I have interesting to write a pure software backend (for some old device that have not OpenGL support or OpenGL support is software and very slow, e.g. the old Nokia cellphones). Is pull requests welcome?

regards,
Xavier.

Cool! Yes, it is indeed way faster in most cases. Far less state changes and only one upload to the GPU. My plan to is to remove the old gl2 and gl3 backends and rename the file to nanovg_glbuf.h or just nanovg_gl.h.

Software backend would be cool! Pull request is welcome, or if you want you can also host it yourself. Let me know if the API to the backend needs some changes. Currently it is geared very much towards GPU rendering.

Yes, to name it nanovg_gl.h and make it the only backend is great!

I'll look into current backend to decide how to make a tiny software backend, quality and speed are all important. I will submit issues if I meed problems. Thanks for help!
