Add another (commented) template in the loop: select a specific set of SVG with searching for a specific markup.

[TXT-ONLY] Convert them all to white-transparent-background. Fix issue of dark edge in Scribus. After usage, I commented the loop as an example in install.sh .

Add PNG option to output white-transparent-background by default. ( ref. Scribus bug report: https://bugs.scribus.net/view.php?id=14842#c43990 )

Revert "[ TXT-ONLY => PDF ] because Scribus rasterize immediately the PDF, adding more transparency issue. Also, vectorized PDF are not 100% WYSIWYG to the SVG ( filters/flowing-text position/blur). Keeping PNG is way more safe."

[ TXT-ONLY => PDF ] Switch text-only renders to PDF instead of PNG. This commit will be immediately reverted, but commited to keep the method: in fact, Scribus rasterize immediately the PDF, adding more transparency issue. Also, vectorized PDF are not 100% WYSIWYG to the SVG ( filters/flowing-text position/blur). Keeping PNG is way more safe.

Use two versions of Inkscape for rendering SVGs. If only one Inkscape is installed, fallback to generic executable 'inkscape' for all.

Adding feature: autodetect , less click ( now depend of Inkscape 0.92.trunk ) and cleaning.
