From 5d64a06a6322b6e6f88233e79c6431e96eda7de6 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Wed, 24 Nov 2010 01:24:38 +0800 Subject: st/vega: Add primitive text support. Optional features such as auth-hinting are not implemented. There is no anti-aliasing, and no effort is done to keep the glyph origin integral. So the text quality is poor. --- src/gallium/state_trackers/vega/text.h | 71 ++++++++++++++++++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 src/gallium/state_trackers/vega/text.h (limited to 'src/gallium/state_trackers/vega/text.h') diff --git a/src/gallium/state_trackers/vega/text.h b/src/gallium/state_trackers/vega/text.h new file mode 100644 index 0000000000..6b3fa7323e --- /dev/null +++ b/src/gallium/state_trackers/vega/text.h @@ -0,0 +1,71 @@ +/************************************************************************** + * + * Copyright 2010 LunarG, Inc.
