Role in this project:Back-end Developer
Back-end DeveloperContributions:21 releases, 308 reviews, 1868 commits in 14 years
Contributions summary:Pierre's contributions focused on abstracting platform rendering to surfaces by modifying the codebase to support more render targets than framebuffers, which allows the viewer to support drawing multiple layers, preventing flickers on certain platforms. This also includes refactoring of the code across multiple files, including changes to the OS X, Win32 and x11 implementations. Further contributions include the modification of a test to include an offscreen buffer for compositing.
