+Some emulation components are better implemented by copying the Flex code and
modifying it. One of the deciding factors is whether there are low-level Flash
APIs used. If not, the component is a candidate for straight migration.
+
+The process is "simple":
+1) Copy the Flex code file.
+2) Rename flash.*.* imports to the Royale equivalents:
+* flash.events.* generally can become org.apache.royale.events.*
+* flash.display.Graphics might be replaced with mx.display.Graphics
+* flash.display.* needs to be replaced by Basic or MXRoyale controls. Sprite
probably gets replaced by UIComponent, for example.
+* flash.text.TextFIeld might be replaced by mx.controls.Label
+3) If the code relies on Flex lifecycle APIs, consider calling
commitProperties in an override of addedToParent(). createChildren() should
get called. measure() may not get called but hopefully there aren't critical
things in measure(). If updateDisplayList is used, override setActualSize() to
call updateDisplayList.
+4) Try to compile it.
+5) Ask on the dev@royale mailing list about any remaining errors.
