Change the BLF_aspect function to handle 3d text.
This is need to properly handle 3d text (dalai work on GE), before
the BLF_aspect only take one argument, and the result was a call to:
glScalef(aspect, aspect, 1.0)
Now the three value are store in the font (x, y and z) and also
need to be enable using BLF_enable(BLF_ASPECT).
By default all the code that don't have BLF_ASPECT enable work with
a scale of 1.0 (so nothing change to the current UI).
I also remove all the call of BLF_aspect(fontid, 1.0) found in
the editors, because is disable by default, so no need any more.
Campbell the only thing to check is the python api, right now
I modify the api to from:
BLF_aspect(fontid, aspect)
to:
BLF_aspect(fontid, aspect, aspect, 1.0)
This is to avoid break the api, but now you need add the BLF_ASPECT
option to the function py_blf_enable and in some point change
py_blf_aspect to take 3 arguments.
