swsurface

This crate provides a software-rendered surface for winit.

The goal of this crate is to provide a minimal drawing functionality for every platform supported by winit even if the drawing APIs that we usually assume are available, such as OpenGL¹, aren't available in the target environment. This crate is also useful as a fallback when they are available, but failed due to an unrecoverable error.

To this end, this crate is designed to panic only when preconditions are not met or under very pathologic circumstances that would cause winit to panic.

Unimplemented features

• Partial update - The application can redraw a portion, but swsurface always sends entire the windowfor now
• Support for platforms other than: macOS, Windows, X11, Wayland
• X11: Support for color depths other than 24
• X11: Transparency
• Multi-threaded rendering (Send-able Surface)
• Color management - we'll try to stick to sRGB for now
