Hi everyone.  I'm doing some custom rendering on a Canvas object, and want
to achieve a visible white glow behind some text. I'm using a Paint object
with a BlurMaskFilter:

Paint p = new Paint();
p.setColor(0xFFFFFFFF);
p.setMaskFilter(new BlurMaskFilter(4f,BlurMaskFilter.Blur.OUTER));

I can see the blur, but it is very very faint. Is there any way to beef up
the alpha values? I tried rendering with this paint object multiple times
and this does make the glow easier to see, but it makes for inefficient
rendering.

Thanks, Rob
