Subject: [PATCH 1/2] ob-latex: Export the full area of the drawing

* lisp/ob-latex.el (org-babel-latex-pdf-svg-process): Add the argument
-D (--export-area-drawing) to avoid sub-point cuts on hi-DPI screens,
where Inkscape sometimes cuts off a single physical pixel from the
exported drawing.

Subject: [PATCH 2/2] ob-latex: Call Inkscape with descriptive arguments

* lisp/ob-latex.el (org-babel-latex-pdf-svg-process): Use descriptive
arguments, such as '--export-area-drawing' instead of '-D', to
optimize for readability and not brevity (which makes sense for
interactive use, which does not apply here).
