Add-on to Bogue.
Cairo is a famous cross-platform 2D graphics library.
The bogue-cairo
library enables the use of Cairo drawing functions
in Bogue's
Sdl_area.
We rewrote Example #50 from the Bogue distribution using Bogue-cairo. Here is the result.
You may compare the original BOGUE circle primitive (and notice that the interpretation of alpha and anti-aliasing is slightly different). The Cairo version is twice as fast.
Compare Bogue's Example #51.
Change the number of circles interactively using a Slider widget.
