TINYGL: Simplify zline.cpp .
...
drawLine was broken for dx = 0 lines.
Also, the split between fillLineGeneric and drawLine, along with the many
parameters exchanged (with obscure names with subtle differences), made
the code hard to understand.
This implementation should be easier to check.
There was no visible CPU usage change.
Fixes GRIM's ticket printer, which are composed of a lot of vertical
segments.

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.
