TODO: did I get the set of operations mandating it right? commit 3a9cb5e59b676b6148c50907ce6eef5441677e36 Author: Luca Barbieri Date: Thu Aug 26 18:09:41 2010 +0200 mesa: respect color clamping in texenv programs (v2) Changes in v2: - Fix attributes other than vertex color sometimes getting clamped commit de26f9e47e886e176aab6e5a2c3d4481efb64362 Author: Luca Barbieri Date: Thu Aug 26 18:05:53 2010 +0200 mesa: restore color clamps on glPopAttrib commit a55ac3c300c189616627c05d924c40a8b55bfafa Author: Luca Barbieri Date: Thu Aug 26 18:04:26 2010 +0200 mesa: clamp color queries if and only if fragment clamping is enabled commit 9940a3e31c2fb76cc3d28b15ea78dde369825107 Author: Luca Barbieri Date: Wed Aug 25 00:00:16 2010 +0200 mesa: introduce derived _ClampXxxColor state resolving FIXED_ONLY To do this, we make ClampColor call FLUSH_VERTICES with the appropriate _NEW flag. We introduce _NEW_FRAG_CLAMP since fragment clamping has wide-ranging effects, despite being in the Color attrib group. This may be easily changed by s/_NEW_FRAG_CLAMP/_NEW_COLOR/g commit 6244c446e3beed5473b4e811d10787e4019f59d6 Author: Luca Barbieri Date: Thu Aug 26 17:58:24 2010 +0200 mesa: add unclamped color parameters --- src/mesa/drivers/dri/i915/i915_fragprog.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/mesa/drivers/dri/i915/i915_fragprog.c') diff --git a/src/mesa/drivers/dri/i915/i915_fragprog.c b/src/mesa/drivers/dri/i915/i915_fragprog.c index 2bfe665cb65..89de2a8b0d3 100644 --- a/src/mesa/drivers/dri/i915/i915_fragprog.c +++ b/src/mesa/drivers/dri/i915/i915_fragprog.c @@ -1291,7 +1291,7 @@ i915ProgramStringNotify(struct gl_context * ctx, */ if (p->FragProg.FogOption) { /* add extra instructions to do fog, then turn off FogOption field */ - _mesa_append_fog_code(ctx, &p->FragProg); + _mesa_append_fog_code(ctx, &p->FragProg, TRUE); p->FragProg.FogOption = GL_NONE; } } -- cgit v1.2.3
