Following jr's good idea and even if you have to use macro, you might as
well make a "complete" one :

#macro MakeCentetText (pText, pFont, pThickness, pOffset, pTexture)
 #local _t = text { ttf pFont pText pThickness, pOffset }
 #local _l = (max_extent(_t).x-min_extent(_t).x)*0.50;
 object { _t translate -_l*x texture { pTexture } }
#end


and using it like this :

object {
 MakeCentetText("some more text", "timrom.ttf", 0.10, 0, myTexture )
 }
