Update the part at the top about how to maintain the file with
more tips.
Add a chapter on "window-system support" describing in a general
way how the support for different window systems/device types
works, including the separation between device-independent and
device-dependent parts, device methods, the specific device types
and the "xlike" pseudo-type.

* toolbar-xlike.c (xlike_redraw_frame_toolbars):
* toolbar-xlike.h:
* toolbar-xlike.h (xlike_clear_frame_toolbars):
Rename some files to make them consistent with general naming rules:
xgccache.c -> gccache-x.c
xgccache.h -> gccache-x.h
toolbar-common.c -> toolbar-xlike.c
toolbar-common.h -> toolbar-xlike.h
Fix include-file references. Also change the names of functions
in now-named toolbar-xlike.c to be xlike_foo() instead of common_foo().
Add a longish comment in console-xlike-inc.h describing the "xlike"
system, how it works and what the various files are used for.

| 50 /* helper function to correctly open Xft/core fonts by name | |
| 51 #### Can't we use FcParseName here? | |
| 52 #### Is this done so often that the logic needs to be hard-coded in C? | |
| 53 | |
| 54 Daniel Pittman sez: Older code tried to enforce that an XLFD font was | |
| 55 not scaled, while this version just doesn't care. I think that is a | |
| 56 better behavior, since if someone really wants a scaled font we should | |
| 57 oblige them. | |
| 58 | |
| 59 Stephen sez: This whole function was ill-conceived, and I'm not sure it | |
| 60 succeeds at any of the things it attempts to do. First, we should be | |
| 61 using fontconfig directly. I'm not sure what Xft (or fontconfig) will | |
| 62 try to do if passed an XLFD. As for scaled fonts, both options are | |
| 63 equally bad. The problem is that the X server will often scale bitmap | |
| 64 fonts willy-nilly; it's worth trying to avoid that, but I can't say | |
| 65 whether that's worth overriding somebody who knows what they're doing. | |
| 66 In any case, I think we should find out what Xft (fontconfig?) is able | |
| 67 and willing to do with XLFDs, and probably move the logic to LISP. | |
