From f5bfe54a34d9c8cd5de2b096d0e8486fe0d990a7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Tue, 27 Sep 2011 22:22:06 +0200 Subject: [PATCH] gallium: add and use PIPE_SHADER_CAP_MAX_TEXTURE_SAMPLERS This removes: - PIPE_CAP_MAX_TEXTURE_IMAGE_UNITS - PIPE_CAP_MAX_VERTEX_TEXTURE_UNITS in favor of the that new per-shader cap.
