Vincent Pelletier 03da50312b TINYGL: Move the task of writing to z-buffer to FrameBuffer::writePixel. 
Because writePixel may decide to not write anything (alpha test), in which
case no z-buffer write should happen.
Factorises code.
Fixes apparent back-face culling in GRIM behind transparent textures, like
the tube (the 3d-shape Manny takes out, not the flat image in foreground)
in set mo.
