SIZE-TEXT returns inaccurate values

[dsunanda]

Expected behavior

Would expect it to return the "bounding box" for the text contained with in it - so, for example:

layout [tb: box 20x200 "Hello^/hello^/hello^/hello"]
tb/size: size-text tb

Would shrink (or grow) TB so that it is neatly the size of the text.

(That's an oversimplification as there are issues with margins and baselines etc -- but it's a useful minimum starting point for boxes that resize to fit their text content. And, without useful output from SIZE-TEXT it not obvious how to accurately resize boxes - or change font sizes - to fit text content).

Actual behavior

SIZE-TEXT in Red always seems to treat the text as being on one line, so with the above example:

SIZE-TEXT tb
==  119x17   ;; almost always x17, except where we erratically get 0x0 under unreproducible conditions

In R2 the same result is more what we'd expect given the default font size, and text wrapping.

== 16x228

I would not expect exactly the same result from Red - its compositing is bound to be different. But I'd expect sometime close.

Steps to reproduce the problem

layout [tb: box 20x200 "Hello^/hello^/hello^/hello"]
size-text tb

I fixed this in #3683 and it's okay to close this one.
From now on:

Windows 7:

>> tb/size: size-text tb
== 31x53

Windows 8:

>> tb/size: size-text tb
== 33x66

MacOS:

>> size-text tb
== 33x68
