===Filling===
To ''fill'' a shape, the first step is to identify which pixels fall inside the shape.  These pixels will be affected by the fill operation.  Pixels that are partially inside and partially outside the shape may be affected to a lesser degree if [[Spatial anti-aliasing|anti-aliasing]] is enabled.

The paint is then asked to generate a color for each of the pixels to be painted.  In the common case of a solid-color fill, each pixel will be set to the same color.

The composite takes the pixels generated by the paint and combines them with the pixels already onscreen to produce the final result.
