Alpha and Text Rendering

Hello,

It seems that the alpha is not taken in account in a good way
with the XftTextRender* and XftDrawString* functions (I do not
check with XRenderCompositeString*). It seems that the computation
of the final color for rendering the text is done always as if
the background was white. In others words
If I used a white (or a light) background the functions work as
expected. But if I used a black (or dark) background and, says,
a white foreground the text color does not depends on the alpha
it is always (fully) white and not greyed at all.

I used XRender and Xft from Xfree 4.2 (same problems with Xft
from the current cvs). I've no problems with XftDrawRec and
XRenderComposite, the alpha "channel/color" is taken in account
in the good way (BTW it is a pleasure to work with XRenderComposite).
