From 7efd71616ec5efedbe626a986a707c35d3cac323 Mon Sep 17 00:00:00 2001 From: wolfbeast Date: Wed, 6 Nov 2019 21:06:15 +0100 Subject: Issue #1274 - Part 1: Adopt the cairo version as our own. - Move header licensing from tri-license to MPL 2.0. MPL-compatible other licensing has been retained where originally present. - Remove individual superseded licensing terms. - Remove patches, outdated readmes & incomplete patch summaries. - Remove incomplete cairo release notes (only went up to 1.6.4 anyway). - Rewrite COPYING to indicate the current state of the library in tree. --- gfx/cairo/win32-raster.patch | 262 ------------------------------------------- 1 file changed, 262 deletions(-) delete mode 100644 gfx/cairo/win32-raster.patch (limited to 'gfx/cairo/win32-raster.patch') diff --git a/gfx/cairo/win32-raster.patch b/gfx/cairo/win32-raster.patch deleted file mode 100644 index 080873121..000000000 --- a/gfx/cairo/win32-raster.patch +++ /dev/null @@ -1,262 +0,0 @@ -changeset: 29338:f2a10f325734 -tag: qtip -tag: tip -tag: win32-raster-mask2.patch -tag: qbase -user: Jeff Muizelaar -date: Mon Jun 22 14:26:07 2009 -0400 -summary: imported patch win32-raster-mask2.patch - -diff --git a/gfx/cairo/cairo/src/cairo-image-surface.c b/gfx/cairo/cairo/src/cairo-image-surface.c ---- a/gfx/cairo/cairo/src/cairo-image-surface.c -+++ b/gfx/cairo/cairo/src/cairo-image-surface.c -@@ -1232,27 +1232,27 @@ typedef struct _cairo_image_surface_span - cairo_composite_rectangles_t composite_rectangles;
