Nice goodie: Preview renders! - Added new preview.blend, allowing super wide cinemascope previews - Draws nicely blended inside widget type, rounded corners - Preview now renders using all available cpus/cores. - Uses - hopefully rock stable - method, which doesn't copy or allocate anything for previews, but just uses render API calls. - Multiple previews are possible! But, added provision in Jobs manager to only render one preview job at a time. If you start more preview jobs, they're suspended until it's their turn. Bugfix: new buttons context code crashed when going full-window. Tweaks are still needed for notifiers. I have to figure out still how to retrieve SpaceButs button view types...
