From c65f580b932daf7492d09c30462bf470247f794d Mon Sep 17 00:00:00 2001 From: Matthias Clasen Date: Sun, 18 Dec 2022 15:13:55 -0500 Subject: [PATCH] Drop hb-test This was a test binary to assist in developing the hb-paint code. Not needed anymore, now that hb-view has the same code in the cairo userfont backend. --- util/hb-test.c | 350 ----------------------------------------------- util/meson.build | 7 - 2 files changed, 357 deletions(-) delete mode 100644 util/hb-test.c diff --git a/util/hb-test.c b/util/hb-test.c deleted file mode 100644 index c984db67a..000000000 --- a/util/hb-test.c +++ /dev/null @@ -1,350 +0,0 @@ -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include "hb-cairo-utils.h" - -static void -move_to (hb_draw_funcs_t *dfuncs, - cairo_t *cr, - hb_draw_state_t *st, - float to_x, float to_y, - void *) -{ - cairo_move_to (cr, - (double) to_x, (double) to_y);
