- * To do:
+ * TODO on fontsel
+ * ---------------
*
- * - import flags to do VT100 double-width; import the icky
- * pixmap stretch code on to the X11 side, and do something
- * nicer in Pango.
+ * - implement the preview pane
*
- * - unified font selector dialog, arrgh!
+ * - extend the font style language for X11 fonts so that we
+ * never get unexplained double size elements? Or, at least, so
+ * that _my_ font collection never produces them; that'd be a
+ * decent start.
+ *
+ * - decide what _should_ happen about font aliases. Should we
+ * resolve them as soon as they're clicked? Or be able to
+ * resolve them on demand, er, somehow? Or resolve them on exit
+ * from the function? Or what? If we resolve on demand, should
+ * we stop canonifying them on input, on the basis that we'd
+ * prefer to let the user _tell_ us when to canonify them?
+ *
+ * - think about points versus pixels, harder than I already have
+ *
+ * - work out why the list boxes don't go all the way to the RHS
+ * of the dialog box
+ *
+ * - develop a sensible sorting order for the font styles -
+ * Regular / Roman / non-bold-or-italic should come at the top!
+ *
+ * - big testing and shakedown!
*/
/*
* or before, if I'm feeling proactive - it oughtn't to be too
* difficult in principle to convert the whole thing to use
* actual Xlib font calls.
+ *
+ * - it would be nice if we could move the processing of
+ * underline and VT100 double width into this module, so that
+ * instead of using the ghastly pixmap-stretching technique
+ * everywhere we could tell the Pango backend to scale its
+ * fonts to double size properly and at full resolution.
+ * However, this requires me to learn how to make Pango stretch
+ * text to an arbitrary aspect ratio (for double-width only
+ * text, which perversely is harder than DW+DH), and right now
+ * I haven't the energy.
