2006-09-21remove rgb[] array from span_arrays_struct - was only used in a few placesBrian Paul

2006-09-13updated commentBrian Paul
2006-08-29Move call to _swrast_update_rasterflags() since it depends on theBrian Paul
results of _swrast_update_fog_state(). Fixes bug where first frame of progs/samples/fog.c does not show fog.

2006-07-20Some structure renaming. Prefix vertex/fragment-related structs withBrian Paul
"gl_" to match other structs.

2006-05-23Add const qualifiers in a number of places.Brian Paul
2006-05-22GL_INDEX_OFFSET didn't work with CI->RGB mappings.Brian Paul
Added some const qualifiers.

2006-04-14don't need s_depth.hBrian Paul
2006-04-14Replace ctx->Const.MaxTextureUnits w/ ctx->Const.MaxTexture[Coord/Image]UnitsBrian Paul
in various places. Note that ctx->Texture.CurrentUnit needs to be tested against Coord/Image limits when referenced, not just in glActiveTexture().
2006-04-11More GLSL code:Michal Krol
- use macros to access and modify render inputs bit-field; - un-alias generic vertex attributes for ARB vertex calls; - use MAX_VERTEX_PROGRAM_ATTRIBS (NV code) or MAX_VERTEX_ATTRIBS (ARB code) in place of VERT_ATTRIB_MAX; - define VERT_ATTRIB_GENERIC0..15 for un-aliased vertex attributes for ARB_vertex_shader; - fix generic attribute index range check in arbprogparse.c; - interface GLSL varyings between vertex and fragment shader; - use 64-bit optimised bitset (bitset.h) for render inputs;
2006-04-06remove unused varBrian Paul
2006-04-06Replace MESA_FORMAT_DEPTH_COMPONENT_FLOAT32 with 32-bit integer format.Brian Paul
This allows render to depth texture (we don't support floating pt. Z buffers). Rename MESA_FORMAT_DEPTH_COMPONENT16/32 as MESA_FORMAT_Z16/32. Software fallback for glCopyTexImage now uses integer temporary image instead of float, eliminates a lot of float/int conversions.
2006-04-05Check/use texture border color when sampling depth textures. (bug 6498)Brian Paul
Silence some warnings.
2006-04-04Fix texcoord interpolation for fragment shaders.Michal Krol
2006-03-29put braces around RENDER_SPAN macro when called, not when defined. Fixes ↵Brian Paul

2006-03-25remove carriage returnsBrian Paul
2006-03-22Need to check for new state and do readpixels/drawpixels clipping afterBrian Paul
we call RENDER_START since that may involve validating the drawable and updating its dimensions.
2006-03-21GLSL fixes:Michal Krol
- generate error on NULL pointers in glShaderSourceARB; - reinstall program object, if current, in glLinkProgramARB; - vertex and fragment shaders are optional in program object; - floor asm was wrongly computed for x86 back-end; - allow for (void) idiom in function prototypes; - all fixed-state uniforms are updated; - local variable initializers are working; - implement texture* and shadow* functions for vertex processor; - generate error if too many arguments in general constructor; - trim unused data in general constructor; - struct r-value field select was badly relocated; Changes: - add derived state gl_fog_attrib::_Scale; - add derived state gl_light::_CosCutoffNeg;

2006-03-03Fix bogus span mask in s_atifragshader.c leading to trouble when the pixel ↵Roland Scheidegger
was later discarded by z test (this fixes doom3 r200 renderpath with swrast). Fix calling _swrast_alpha_test potentially leading to bogus results when Alpha Test might not be enabled. While here, don't disable deferred_texture (early z) when ATI_fragment_shader is active, as it is not necessary (for the record, this boosts doom3 swrast performance by roughly a factor of 2 (4 seconds per frame now...) with the r200 render path, might be a worthwile optimization for fragment programs which don't write z).
