It worked without it, but better safe than sorry.

They all are very similar but still differ in subtle ways.

eeshow/cro.h (cro_img_end, cro_img_write, cro_canvas_end): don't need void *
...
Since we don't call these functions through gfx_ops, we don't need
a void pointer.

eeshow/cro.c: set line cap to CAIRO_LINE_CAP_ROUND or CAIRO_LINE_CAP_SQUARE
...
CAIRO_LINE_CAP_ROUND is the same as in FIG mode.
Note that all non-dashed lines disappear when generating PDF and
CAIRO_LINE_CAP_ROUND is set. For now, we just use CAIRO_LINE_CAP_SQUARE.

eeshow/cro.c (cr_pdf_end): reduce line width to 0.5 * scale
...
With 2, lines were far too thick. Note that the 0.5 points (1/72 in) we
have now are roughly twice what XFig uses (1/160 in for PDF or PNG),
yet things don't look very fat there.
