Faster than C2DGraphics?

[PanosMich]

I need to draw a very large polyline in a framebuffer for fast panning. Is this library faster than Circle's C2DGraphics? Can it draw in a framebuffer to achieve fast panning? How complete is this capability?

There is a complete OpenVG 1.1 implementation for RPi 1-3 (32-bit) in Circle, which allows to do fast vector graphics. The C++ wrapper in libgraphics is far from complete, but if you work with the native C OpenVG API, you should be able to do everything you want. Here is some info:
