Just some early advice that I expect to have a very close emulation of the flash graphics API available by early January at the latest. I had a client express a need for this, and I have quite a lot of progress already. I know we have various graphics support already in Graphics and MXRoyale, but the emphasis for this will be on the closest match to swf that I can reasonably achieve. I'm reasonably familiar with this stuff from things I have done in the past (although much of that was 10-12 years ago now).
There are some things that, while technically possible may not be 'practical' to emulate based on how heavy the code would be to achieve that in JS. One of these is the miter joint implementation in flash which is not currently available in a similar way in svg. Unfortunately it seems that will not be available in svg 2.0 even though it was intended to be. Also some browser/OS combinations seem to not handle certain gradients very well. In general windows is better than mac for these, and Safari on Mac seems to be the most problematic so far. I did not focus a lot on mobile, but things were working quite good in a 2013 Galaxy Tablet, for example. Anyhow I just wanted to let others know I was working on this, and hope to share progress soon. -Greg
