avm2: Implement DisplayObject.transform and most of Transform
This PR implements the 'DisplayObject.transform' getters/setters,
and most of the getters/setters in the `Transform` class
From testing in FP, it appears that each call to the
'DisplayObject.transform' property produces a new
'Transform' instance, which is permanently tied to the
owner 'DisplayObject'. All of the getters/setters in
`Transform` operate directly on owner `DisplayObject`.
However, note that the `Matrix` and `ColorTransform`
valuse *produced* the getter are plain ActionScript objects,
and have no further tie to the `DisplayObject`.
Using the `DisplayObject.transform` setter results in
values being *copied* from the input `Transform` object.
The input object retains its original owner `DisplayObject`.
Not implemented:
* Transform.concatenatedColorTransform
* Transform.pixelBounds
When a DisplayObject is not a descendant of the stage,
the `concatenatedMatrix` property produces a bizarre matrix:
a scale matrix that the depends on the global state quality.
Any DisplayObject that *is* a descendant of the stage has
a `concatenatedMatrix` that does not depend on the stage quality.
I'm not sure why the behavior occurs - for now, I just manually
mimic the values prdduced by FP. However, these values may indicate
that we need to do some internal scaling based on stage quality values,
and then 'undo' this in certain circumstances when constructing
an ActionScript matrix.
Unfortunately, some of the computed 'concatenatedMatrix' values
are off by f32::EPSILON. This is likely due to us storing some
internal values in pixels rather than twips (the rounding introduced
by round-trip twips conversions could cause this slight difference0.
For now, I've opted to mark these tests as 'approximate'.
To support this, I've extended our test framework to support providing
a regex that matches floating-point values in the output. This allows
us to print out 'Matrix.toString()' and still perform approximate
comparisons between strings of the format
'(a=0, b=0, c=0, d=0, tx=0, ty=0)'
