ggpattern includes versions of (nearly) all geoms from ggplot2 which could plausibly support being filled with a pattern.
See the vignette galleries for examples of all the available geoms filled with geometry-based patterns and image-based/array-based patterns.

There are also scale functions to control each of these new aesthetics e.g. scale_pattern_alpha_discrete.
Not all aesthetics apply to all patterns. See the individual pattern vignettes for which aesthetics it uses, or see the first vignette on developing user-defined patterns for a table of aesthetic use by pattern, or see the individual vignettes for each pattern.

Users can write their own pattern functions and ask ggpattern to use them, without having to include the pattern in the package.
See the vignette on developing patterns: vignette("developing-patterns", package = "ggpattern").
Note: due to CRAN package size limits many of these vignettes are only available in the Github version of {ggpattern} and the package website.
