Description
I've found that setting strings longer than about 50 characters crawls to a halt. Sometimes crashes. A simple fix would be to just not animate if the length is greater than a certain number. I attempted to do this by modifying the setter for the text variable, pausing the display link and setting super.text to the value if it was above a threshold. This sometimes works, but I think I'm missing something, as I still get issues with performance. Advice appreciated. Would love to use this in the next rev of Slated if I can get it reliable.

Research direction
Start by reproducing the slowdown and crashes with strings longer than about 50 characters, then inspect the text setter and display-link handling described in the issue. Done means long strings remain usable without severe performance degradation or crashes, including when animation is bypassed.
