Support multi sampled anti-aliasing with wxWidgets 3.0.3. #3343
This patch improves rendering of the 3D scenes. The improvement is significant on the 3D path simulation.
Some good practices for making contributions to Slic3r (IMHO, any upstream project).
The less work the project maintainers have to do to vet and merge external code, the more likely it will be that (all other things being equal) the code gets merged in.
As a quick example, see #3349 . I created a branch on my personal fork of Slic3r, lordofhyphens:feature-1333 which originated at alexrj:master. I made the changes, tested them, and then committed them to that branch. Then the pull request got made. When the PR gets merged in (I tend to not merge my own commits in, so someone else can check them as a guard against me derping), I'll delete the branch from my own repo.
I've had my own learning curve with this too with my first few PRs for Slic3r, so I am happy to try to help you too. :)
