text2d leadscale and bline

Dg's icon

I trying to do some very slow text movements.

I'm working with bline, but the leadscale message drived by bline gives me really bad results.

Since dim values for [jit.gl.text2d] are not the resolution of the matrix but the #of caracters I don't see what to increase, but speed ... which is not what I want.

Is there a way to smooth more the leadscale with slow interpolation (bline) values?
