Function do_mask(texture,maskr=0,maskg=0,maskb=0)
	maskcol=(maskr Shl 16)+(maskg Shl 8)+maskb
	LockBuffer TextureBuffer(texture)
	For x=0 To TextureWidth(texture)-1
		For y=0 To TextureWidth(texture)-1
			pix=ReadPixelFast(x,y)
			If (pix And $FFFFFF)=maskcol WritePixelFast x,y,(pix Or $FF000000) Else WritePixelFast x,y,0
		Next
	Next
	UnlockBuffer TextureBuffer(texture)
End Function

Another alternative -
create texture, draw to it, then send it to the above function specifying the (r,g,b) value you want to be c-thru
(defaults to black 0,0,0)
