From ef39ccbbe81a0e13875093d3665faf0b0ef1d756 Mon Sep 17 00:00:00 2001 From: Kenichi Handa Date: Wed, 14 May 2008 00:40:04 +0000 Subject: [PATCH] : Throughout the file, delete all USE_FONT_BACKEND conditionals. Don't check enable_font_backend. Delete all codes used only when USE_FONT_BACKEND is not defined. Surround non-used code by "#ifdef OLD_FONT" and "endif". --- src/w32term.c | 276 +++++++++++++++++++------------------------------- 1 file changed, 105 insertions(+), 171 deletions(-) diff --git a/src/w32term.c b/src/w32term.c index a40fe2edc48..b7332ed25f9 100644 --- a/src/w32term.c +++ b/src/w32term.c @@ -59,10 +59,8 @@ Boston, MA 02110-1301, USA. */ #include "w32bdf.h" #include -#ifdef USE_FONT_BACKEND #include "font.h" -#endif /* USE_FONT_BACKEND */ - +#include "w32font.h" /* Fringe bitmaps. */ @@ -896,6 +894,8 @@ w32_reset_terminal_modes (struct terminal *term) /* Function prototypes of this page. */ +#if OLD_FONT + XCharStruct *w32_per_char_metric P_ ((XFontStruct *, wchar_t *, int)); static int w32_encode_char P_ ((int, wchar_t *, struct font_info *, struct charset *, int *)); @@ -1140,7 +1140,6 @@ w32_cache_char_metrics (font) } } - /* Determine if a font is double byte. */ static int w32_font_is_double_byte (XFontStruct *font) @@ -1483,6 +1482,7 @@ w32_text_out (s, x, y,chars,nchars) nchars * charset_dim, NULL); } +#endif /* OLD_FONT */ static void x_set_glyph_string_clipping P_ ((struct glyph_string *)); static void x_set_glyph_string_gc P_ ((struct glyph_string *)); @@ -1594,11 +1594,6 @@ x_set_mouse_face_gc (s) /* If font in this face is same as S->font, use it. */ if (s->font == s->face->font) s->gc = s->face->gc; -#ifdef USE_FONT_BACKEND - else if (enable_font_backend) - /* No need of setting a font for s->gc. */ - s->gc = s->face->gc; -#endif /* USE_FONT_BACKEND */ else { /* Otherwise construct scratch_cursor_gc with values from FACE @@ -1692,11 +1687,7 @@ static INLINE void x_set_glyph_string_clipping (s) struct glyph_string *s; { -#ifdef USE_FONT_BACKEND RECT *r = s->clip; -#else - RECT r[2]; -#endif int n = get_glyph_string_clip_rects (s, r, 2); if (n == 1) @@ -1714,9 +1705,7 @@ x_set_glyph_string_clipping (s) DeleteObject (clip2); DeleteObject (full_clip); } -#ifdef USE_FONT_BACKEND s->num_clips = n; -#endif /* USE_FONT_BACKEND */ } /* Set SRC's clipping for output of glyph string DST.
