It would be great to add a function canvas_circle to drawille.sh, that would take four parameters: x and y coordinates of the center and radius in pixels and last parameter that would decide if it should use canvas_ser or canvas_unset to draw the pixels of the circle. This function would then draw a circle with specified parameters into pixel_buffer using canvas_set or canvas_unset.
Bonus points if we could also get a test script featuring this new function.

The pixel matrix has some minor bugs. I have noticed that the problem occurs only in X dimension. For example, some rows consist of 130 pixels, while another consist of 128. Probably that's the reason why they are blanks when drawing the vertical lines of the border.
