2005-09-16Fix potential segfault when trying to read pixels outside renderbuffer bounds.Brian Paul
Use _swrast_get_values() which does clipping.
2005-06-02Remove last of the old span code.Brian Paul
2005-05-04Major check-in of changes for GL_EXT_framebuffer_object extension.Brian Paul
Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
2004-01-28s/BlendEquatioRGB/BlendEquationRGB/Brian Paul
2004-01-27Added support for EXT_blend_equation_separate / ATI_blend_equation_separate.Ian Romanick
The internal driver interface was also changed to use BlendEquationSeparate instead of BlendEquation.

2003-06-05Removed all RCS / CVS tags (Id, Header, Date, etc.) from everything.Ian Romanick
2003-03-25replace _mesa_ prefix with _swrast_, remove s_histogram.[ch]Brian Paul
2002-10-17patches from Gerk Huisma for float-channel renderingBrian Paul
2002-08-07struct sw_span is again allocated on the stack, but the arrays of spanBrian Paul
data are broken out into a new struct span_arrays which is allocated per-context (to avoid huge stack allocations - a problem on Windows). This lets us use span.redStep instead of span->redStep (for example) to hopefully get slightly better performance in the triangle functions.

2002-02-02Converted line drawing over to new span code, pb no longer used.Brian Paul
Big clean-up of line drawing code. Removed many obsolete span processing functions.
2002-02-02sw_span can now hold x/y arrays of fragment positions - getting ready toBrian Paul
ditch the pb (pixel buffer) code. Converted point drawing, bitmaps and aa lines to use new span functions.
