[PATCH libXrender] Fix request length calculation for XRenderCompositeText32

[Clemens Eisserer]

Hi,

Request length calculation inside XRenderCompositeText32 is broken for
the case where the number of glyphs fits exactky inside the last
xGlyphElt.
In XRenderCompositeText8 and XRenderCompositeText16 this case is
handled properly, somehow the "-1" got missing in
XRenderCompositeText32.
