JavaFX graphics performance and suitability for advanced animations

[Richard Bair]

This is the issue: https://javafx-jira.kenai.com/browse/RT-6475

Lets carry on the conversation there about the API. Basically what we need is a simple API on Text (which we can then also add to Labeled) that allows you to pick the rendering mode. Right now we're picking it for you (and happen to pick the one that gives really great smoothness but only in the case that the text is large, otherwise we resort back to glyphs), but you need to have some kind of control in these cases. I thought that cache & cacheHint would do the trick, but it appears to not be working (and even if it did it means rendering the entire text into a texture which may or may not be good depending on the use case).

Hmmmm. I wonder if you used an 81pt font and scaled it down what that would look like?
