BifDisplay node is mentioned in Video fields, but is not fully documented. No examples provided.

On this page https://sdkdocs.roku.com/display/sdkdoc/Button
are incorrect default values for iconUri, focusedIconUri

Additionally, for Button if using an image with a size larger than maxwidth, if  minWidth is not set, seems it's defaulting to the width of the image and therefore minwidth must be set to decrease the size. (what I would expect maxwidth to do)
if I set maxwidth only (and no minwidth), the button is much wider than the maxwidth value.  if set minwidth only (and no maxwidth), the button is the width of minwidth.  seems something's mixed up here, or is it just me?
thanks

Seems to me the description (Use) for fieldToInterp is wrong, says should be separated by colon but that doesn't work (for me on Roku 3, targetting opacity), needs to be separated by a dot;

separated by a colon. For example, "title:width"  <---- what's there now

separated by a dot. For example, "title.width"    <---- what it should probably be

(PS. rNB: fixed)

lineSpacing - default is reported as 0
however, testing this, it's not 0.
The default looks to be something like 10.

It seems like the instructions about height are wrong, assuming the Label's height field should automatically update once the text is set?

Request: Please expose the "computed height" of the label after text update?

Duplicate field 
showRowCounterForShortRows is listed twice in the field column on https://sdkdocs.roku.com/display/sdkdoc/RowList

Can we get more information on callFunc? It's use is incorrectly documented. It says you need to pass in an args object, with the fields. that is not true.  I have callfunc uses throughout my app that pass in strings/nodes, etc

ie.. callfunc("sayhello", hello)

function SayHello(message as string)
return "hello " + message
end function

that works fine.

Also - no information at all about getting return values from callfunc - you can do this
myValue = aNode.callFunc("SayHello", "George") 
? myValue >> "hello George"

And what's the cost of that? what happens with rendesvous? marshalling? What thread? What scope. Performance cost?

I reckon callfunc could be far more useful, and lead to some nice patterns; but it needs more documentation!
