partial transparency persists, even to new frame drawing events.

[ddyer0]

the partial transparency which is used to anti-alias the arrow persists for the life of the frame,
even after the arrow is no longer being drawn.

I initially thought this was a "metal" problem, but it's present in both the old and new rendering schemes
on IOS. Android is fine.

the frame is supposed to be rendered like this

Will be solved by new build hint that will let you specify the colorspace.

i don't think this is colorspace issue. the yellow arrow isdrawn with 40% transparency, and somehow that
transpareny is becoming permanent, even when the arrow is no longer being drawn.

the actual code that manipulates the opacity expects graphics.getColor() to return an object
which will restore both color and opacity. Apparently it doesn't. and the rest of the frame would
be drawn with the leftover opactiy. However. in this case the arrow is the last thing to be
drawn.

The serious effect is that the NEXT frame which starts with a new graphics context is inheriting
the leftover opacity from the previous frame.

Note that there is a graphics.setOpacity method, but there is no graphics.getOpacity method.

We fixed a different issue related to alpha but it's hard to tell without test cases. You can see our graphics tests here: https://github.com/codenameone/CodenameOne/tree/master/scripts/hellocodenameone/common/src/main/java/com/codenameone/examples/hellocodenameone if you think there are things that are missing in the coverage then let us know.

im never sure when you fixes should become public, but if this persists for a week i'll create a test.

We always release on Friday. Metal landed last Friday (you can see the release date/time in the home page under releases). We will have a new version of metal within a week from the last release.

the word "releases" doesn't appear on your home page. Link?
