For a long time now, MATLABers have been calling for an improved graphics pipeline. MathWorks have made it clear in the past few years that they are working on such an improvement, which has been codenamed HG2. It may or may not even appear in the next MATLAB release*. When it does arrive, I think it's worth measuring it against the things people have been asking for.
So my question is:
What improvements over the current graphics pipeline would you like to see in HG2?
Please put one improvement per answer, and vote for improvements you also want to see.
*Those of you who have seen the Release Notes for R2014b will already know whether HG2 will make its debut in it. Given the terms of using the prerelease, I couldn't possibly comment.
