I am no expert on this, but I have done this before and I think 
bitmap_left and bitmap_top are the needed values to add to the pen 
location to render at. I don't understand where you get g.xoffset / 
g.yoffset from in your code. 

Probably you applied some shift at the time you store the bitmap in the 
texture, but you did not show that code (or I didn't saw it)
