Items related to wgpu and its integration in nannou!
WebGPU is the portable graphics specification that nannou targets allowing us to write code that is both fast and allows us to target a wide range of platforms. wgpu is the name of the crate we use that implements this specification.
The nannou_wgpu crate re-exports the entire wgpu crate along with all of its
documentation while also adding some additional items that makes wgpu easier
to use alongside nannou.
The image feature enables easier interoperation with the image crate,
including functions for uploading textures from image files.
The capturer feature provides the wgpu::TextureCapturer API that aims to
simplify the process of downloading textures from the GPU and easily save them
as image files. As an example, this is particularly useful for recording the
contents of a window or sketch.
Note that when using nannou_wgpu via nannou::wgpu, both features are enabled
by default.
