Filter-GRADIENTGLOWFILTER is not parsed correctly.

[Tao Liang]

I found the following code snippet from swftypes.cpp is not correctly work as SWF-SPEC expected:

stream >> v.BlurX;
 stream >> v.BlurY;
 stream >> v.Strength;
 BitStream bs(stream);
 v.InnerGlow = UB(1,bs);
 v.Knockout = UB(1,bs);

There are two fileds lost:
Angle FIXED Radian angle of the gradient glow
Distance FIXED Distance of the gradient glow
