Misc changes

Common fixes/changes

• In file ./libhtmlw/HTMLfonts.c (about line 84):
  abort();
is commented out (due to an algoritm of font choosing it's normal that program can come in this point.)

• In file ./src/navigate.c (about line 55):
  in function mo_forward_impossible() the following was uncommented:
  /*mo_popup_set_something("Forward", XmxNotSensitive, NULL);*/

• In file ./src/navigate.c (about line 318):
  In functions mo_back() and mo_forward() 'abort()' replaced to 'return'
  (or mMosaic crashed when using buttons for back and forward)

• In file ./src/gui-popup.c (about line 69):
  In function hotmenu_cb() the following was added (to enable forward and backward from popup):
  act_struct *acst = (act_struct *) clid;
  (*(acst->act_code))(w, (XtPointer) acst->win, calld);
  

• In file ./src/paf.c (about line 329):
  Error dialog was created twice, to prevent it in function MMErrorPafDocData the following line was commented:
  XmxMakeErrorDialog(win->base, reason , "Net Error");

• In file ./libhtmlw/HTML.c (about lines 878, 884):
  To enable horisontal scrollbar the following was added:
  if (XtIsRealized(hw->html.hbar))
XtMapWidget(hw->html.hbar);
...
if (XtIsRealized(hw->html.hbar))
XtUnmapWidget(hw->html.hbar);
and line
  XtUnmanageChild(hw->html.hbar)
was commented out because it makes mMosaic a bit slow.

• In file ./libhtmlw/HTML.c (about line 875):
  if (hw->html.doc_width > hw->html.view_width) {
was changed to:
  if (hw->html.doc_width > hw->html.view_width + 2) {
(otherwise horisontal scrollbar don't go away)

• In file ./src/picread.c (about line 269):
  the following line was commented out (program just tried to read not a bitmap file):
  fprintf(stderr, "[ReadXbmBitmap]Line too long.\n");


• In file ./src/gui.c (about line 912):
  Function mo_view_keypress_handler()
  Added functionality for PageUp/PageDown, Alt-Left, Alt/Right (as in netscape)

• In file ./src/paf.c (about line 804):
  the following was uncommented (to fix search problems):

  /* Every time we view the document, we reset the search_start
/* struct so searches will start at the beginning of the document. */
((ElementRef *)win->search_start)->id = 0;
win->src_search_pos = 0;

• In file ./src/gui-dialogs (about line 1582):
  The following was added to make a text widget in the search form to be a default widget:
  XtVaSetValues(search_form, XmNdefaultButton, win->search_win_text, NULL);

• In file ./src/URLparse.c (about line 226):
  There was a bug: after loading a local file new URL was not properly parsed.
  The following condition was added (to ignore the old path in this case):
  (given.host && !related.host)

• In file ./libhtml/HTML.c (about line 281):
  One line was commented out.

• default for parameter WbNmaxColorsInImage changed from 50 to 256

• In file ./src/main.c (about line 176) function RealFatal:
  signal(SIGILL, 0); replaced to signal(SIGKILL, 0);

• In file ./src/gui.c - file pixmaps.h was included twice, one include removed.
  

Creation of mMosaic library (shared)

• New file:
  ./src/mosaic_window.h
  (used to call mMosaic from another program)
  

• In file ./src/main.c:
  Function main() changed to mosaic_main()
  New function mosaic_window() (with a custom event loop).
  New global variables:
  /* for custom event loop */
int endLoop = 0;
/* for initialization of mosaic */
int mosaicMain = 0;
Some functionality was moved from mosaic_main() to mosaic_window()
  In function mo_exit():
  exit(0); replaced to endLoop = 1;

• In file ./Makefile:
  New PIC flag in prerelease flags.
  Variables pnglibs and jpeglibs were changed to shared variant.
  (currently these libs linked statically but can be linked as shared).
  Flag '-G' was added to ldflags.

• In file ./src/Makefile:
  New target LIB_SO (shared library)
  (png and jpeg libs linked as static while all system libs - as shared)

Standalone mMosaic

Using private colormap from another application (parent)

• New files ./src/approx_colors.h ./src/approx_colors.c
  Before creating top-level widgets a function FixMotifColors()
  (from ./src/approx_colors.c) is called which changed default colors for a widget tree.

• In file ./libhtmlw/HTML.c:
  in function HTMLSetHTMLmark() lines for restoring default colors are commented out.

• In file src./xpmread.c (about lines 913, 1002):
  if call to XQueryColor() failed, then called a function near_color() (from ./src/approx_colors.c).

Problems

• Cache not always working properly.

• hidden INPUT values in forms not working.

• INPUT type="image" not working.

• After changing a colormap the colors of pixmap toolbar icons can be bad.

• Postscript converter broken.
  (and it seems hopeless to get it running, maybe an external converter like html2ps can be substituted).
