Replacing French w/ new content from tuxpaint-docs

Some already-translated (but very out-of-date) content
has been replaced with not-yet-translated (i.e., English) content.

Translators may want to look at the previous revisions of these
files when translating the new 'tuxpaint-docs' gettext catalog.
Sorry to cause extra work here, if I've done so.

+About SVGs
+
+   SVG (Scalable Vector Graphics) is an open standard used to describe
+   two-dimensional vector graphics. It is great for diagrams and shapes,
+   while PNGs are better for photographs. SVG files are a bit like
+   instructions on how to make an image. This means that they can be resized
+   without looking pixelated or blocky.
+
+   For more information, visit: https://www.w3.org/Graphics/SVG/
+
+How to make SVGs
+
+   An excellent tool with which to create SVG images for use in Tux Paint is
+   Inkscape, a high-quality Open Source interactive drawing program.
+
+   It is likely that is already installed on your system. If not, it should
+   be readily available from your Linux distribution's software repository.
+   If not, or to learn more, visit http://www.inkscape.org/, respectively.
