Follow-up Comment #11, bug #49053 (project octave):

Here is a patch that is a beginning to fixing the problem. This fixes the
problem of the axis size and axis label scaling. I have another patch that
fixes the font size scaling for other text object, but the problem is that
they are overlapping the axis label. I suspect there are going to be a ton of
places where position/size will need to be scaled by the screen scale.

I also don't know the guts of the handle graphics subsystem well enough to
have added another property. I suspect we want the screen scale to be a
top-level property, rather than a variable in gl_renderer and GLCanvas like I
did in this patch.

I can continue to work on this, but was wondering if the the handle graphics
system is abstracted enough that there are easy-to-find places where
screen_scale should be applied?

(file #38835)
