[mythtv] MMX/3DNow!/SSE OSD blends

[Andrew Mahone]

Isaac, am I misundstanding this code, or is all of the code that's using 
pow_lut pretty much identical?  In other words, would it be sensible to to 
code one function which blends an alpha-masked region onto another 
alpha-masked region, and have it used by ttfont and osdtypes as well?

If I'm not mistaken, it looks like that might be the best direction to go w/ 
this.  This should save some code duplication, as the common blending code 
can be replaced by a call to blendregion or blendregion_mmx, or whatever 
you'd prefer to call them.

In any case, I'll be working along these lines, and should have something 
fairly shortly (probably day or 2 to a week, now that I'm actually coding).
