* fix broken two-sided stencilBrian2007-11-301-0/+3

* simplify INIT_SPAN codeBrian2007-06-291-1/+4
|
* Overhaul/simplify SWvertex and SWspan attribute handling.Brian2007-05-201-71/+57
| | | | | Instead of separate fog/specular/texcoord/varying code, just treat all of them as generic attributes. Simplifies the point/line/triangle functions.
* trim down the number of line drawing functions, special casesBrian2007-04-241-31/+3
|
* remove SWvertex->fog field, use attrib fieldBrian2007-04-231-2/+3
|
* Improve the code for interpolating fragment attributes a little. More to ↵Brian2007-04-231-22/+19

| * Use GLuint instead of GLint to store intermediate Z values. Fixes problems ↵Brian2007-01-061-5/+6
| | | | | | | | when using 32-bit Z buffer.
* | Merge SWvertex texcoord and varying fields into attrib[] array field.Brian2007-02-051-56/+25
| | | | | | | | | | Fragment texcoords and varying code is now unified in the point/line/triangle rasterization code. In the future, merge color, fog, etc. attribs.
* | Replace color, z, w, texture interpolants with new generic attrib interpolants.Brian2007-02-021-35/+36

* | New span attrStart/attrStepX/attrStepY fields to replace fog, specular, etc. ↵Brian2007-02-021-18/+19

* Major check-in of changes for GL_EXT_framebuffer_object extension.Brian Paul2005-05-041-1/+2
| | | | | | | Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
