From 4d24b639d160fe485a3e8f7395e7654538be29e0 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Sat, 21 Feb 2009 13:59:29 -0700 Subject: mesa: use an array for default texture objects Replace Default1D/2D/3D/Cube/etc with DefaultTex[TEXTURE_x_INDEX]. The same should be done with the Current1D/2D/3D/etc pointers... --- src/mesa/main/context.c | 75 +++++++++++++++++------------------------------- src/mesa/main/mtypes.h | 14 ++------- src/mesa/main/texobj.c | 35 +++++++++++++--------- src/mesa/main/texstate.c | 38 ++++++++++++++---------- 4 files changed, 72 insertions(+), 90 deletions(-) diff --git a/src/mesa/main/context.c b/src/mesa/main/context.c index 9705fd8a98..04848794aa 100644 --- a/src/mesa/main/context.c +++ b/src/mesa/main/context.c @@ -423,6 +423,7 @@ one_time_init( GLcontext *ctx ) static GLboolean alloc_shared_state( GLcontext *ctx ) { + GLuint i;
