a filename causes an error instead of generating a trash filename
or crashing, while (2) "plot pnm" with a filename that has the ".pnm"
extension does not add another ".pnm" extension to the end of it.
This commit makes the code (mostly) C99-compatible, enabling to compile
it without the -Wno-error=implicit-function-declaration flag. This
way, Magic becomes usable on arm64 architectures, specifically on Apple
computers with M1/M2 SoC.
traditionally been kept for backwards compatibility. However, the
operation of "ext2spice" and "ext2sim" as separate programs has
become extremely difficult to maintain, and so it has been dropped
in favor of folding both into the program as commands, as was done
a long time ago in the Tcl/Tk version.
from the layout window. The main reason for this is to keep the
box out of the image when doing "plot svg". The "plot" command was
also modified to always do a plot of the entire cell in the active
layout window if the box is not present.
(scrollbar, title bar, etc.) from the output if the command is
called from the non-GUI-wrapper environment (where the border area
is part of the rendered output). This was required due to an
unsolved bug in which calling magic to write SVG output from the
wrapper in some pathological case exposed a Tk bug that caused
the Tk grid manager to infinite loop, filling memory without
limit.
Cairo graphics package (magic -d XR), will map the display onto
an SVG surface and save it to a file using the Cairo SVG backend.
Due to the simplicity of the mapping, there are no options to this
plot command; it just creates a file that is a (scalable!)
replica of the layout window.
