2 * Unified font management for GTK.
4 * PuTTY is willing to use both old-style X server-side bitmap
5 * fonts _and_ GTK2/Pango client-side fonts. This requires us to
6 * do a bit of work to wrap the two wildly different APIs into
7 * forms the rest of the code can switch between seamlessly, and
8 * also requires a custom font selector capable of handling both
16 #include <gdk/gdkkeysyms.h>
19 #include <X11/Xutil.h>
20 #include <X11/Xatom.h>
29 * - it would be nice to have a display of the current font name,
30 * and in particular whether it's client- or server-side,
31 * during the progress of the font selector.
33 * - all the GDK font functions used in the x11font subclass are
34 * deprecated, so one day they may go away. When this happens -
35 * or before, if I'm feeling proactive - it oughtn't to be too
36 * difficult in principle to convert the whole thing to use
37 * actual Xlib font calls.
39 * - it would be nice if we could move the processing of
40 * underline and VT100 double width into this module, so that
41 * instead of using the ghastly pixmap-stretching technique
42 * everywhere we could tell the Pango backend to scale its
43 * fonts to double size properly and at full resolution.
44 * However, this requires me to learn how to make Pango stretch
45 * text to an arbitrary aspect ratio (for double-width only
46 * text, which perversely is harder than DW+DH), and right now
47 * I haven't the energy.
51 * Ad-hoc vtable mechanism to allow font structures to be
54 * Any instance of `unifont' used in the vtable functions will
55 * actually be the first element of a larger structure containing
56 * data specific to the subtype. This is permitted by the ISO C
57 * provision that one may safely cast between a pointer to a
58 * structure and a pointer to its first element.
