2010-02-19mesa: replace _mesa_bzero() with memset()Brian Paul
2010-02-19Remove _mesa_memset in favor of plain memset.Kenneth Graunke
This may break the SUNOS4 build, but it's no longer relevant.
2010-01-15swrast: fix broken _swrast_depth_clamp_span()Brian Paul
The integer Z clamping range depends on the number of bits in the Z buffer because that's the scale factor used when we transform NDC coords by the viewport/depth range. Fixes fd.o bug #25972 but only for Z buffers up to a depth of 30 bits. Beyond that we get into messy integer overflow issues and things fall apart.

2009-10-29mesa: Mostly fix swrast's ARB_depth_clamp support.Eric Anholt
I'd written a testcase for the hard part of the extension enablement, so naturally the easy stuff was completely broken. There are still issues, as I'm seeing FLOAT_TO_UINT(max_f) == 0x0 when max_f == 1.0, but it gets piglit depth-clamp-range closer to success.

2009-10-08mesa: remove a bunch of gl_renderbuffer fieldsBrian Paul
_ActualFormat is replaced by Format (MESA_FORMAT_x). ColorEncoding, ComponentType, RedBits, GreenBits, BlueBits, etc. are all replaced by MESA_FORMAT_x queries.

2009-09-08mesa: Add support for ARB_depth_clamp.Eric Anholt
This currently doesn't include fixing up the cliptests in the assembly paths to support ARB_depth_clamp, so enabling depth_clamp forces the C path.
2008-10-07mesa: pass 'mask', not NULL to renderbuffer->Put functionsBrian Paul
Fixes bug 17800.
2008-09-18mesa: prefix a bunch of #include lines with "main/".Brian Paul
This is another step toward removing a whole bunch of -I flags from the cc commands. Still need to address driver code...
2007-04-21Remove the !rb->Data check that was added a few months ago.Brian
Was changed while debugging #7205. Broke the shadowtext demo. Revisit this if the problem w/ bug 7205 returns...
2007-03-15add some rb->Data null ptr checks (bug 7205)Brian

2006-10-01New SWspan and SWspanarrays typedefs.Brian Paul
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.
2006-03-29fix a GLuint vs GLushort test, new assertionsBrian Paul

2005-11-16Use new gl_framebuffer _Depth/_StencilBuffer fields instead ofBrian Paul
Attachment[BUFFER_DEPTH/STENCIL].Renderbuffer. The former may be wrappers around combined depth/stencil renderbuffers attached at the later points.

2005-09-21add missing scale factor in _swrast_read_depth_span_float()Brian Paul
2005-09-20some improvements to _swrast_clear_depth_buffer()Brian Paul
2005-09-16Fix potential segfault when trying to read pixels outside renderbuffer bounds.Brian Paul
Use _swrast_get_values() which does clipping.
2005-09-16remove unused _swrast_read_depth_span()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.

2002-10-24Header file clean-up:Brian Paul
1. Remove all.h and PC_HEADER junk. 2. Rolled mem.c and mem.h into imports.c and imports.h 3. Include imports.h instead of mem.h Restore _mesa_create/initialize_context() to be like they were in 4.0.4 New wrappers for a few std C functions: _mesa_atoi(), _mesa_strstr(), etc.
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.
2002-04-19casts to fix GLint/GLuint mismatchesBrian Paul

2002-04-12Klaus Niederkrueger's latest changes: use INIT_SPAN() to init span primitiveBrian Paul
type, width, interp mask and array mask.
2002-03-19Use MESA_PBUFFER_ALLOC/FREE macros to allocate all framebuffer and textureBrian Paul
memory. These can be overridden by applications which need to manage this memory specially. Contributed by Gerk Huisma. Also, new code for 8-bit -> 16-bit/channel texture image storage which fills in the least-significant bits properly.
2002-03-16Lots of changes related to framebuffer/window buffer resizing. Basically,Brian Paul
instead of passing a GLcontext* to ResizeBuffers(), pass a GLframebuffer*. The idea is that a window can be resized without it being bound to a rendering context. This makes for a nice clean-up in the XFree86 server-side GLX code. Renamed ctx->Driver.ResizeBuffersMESA() to ctx->Driver.ResizeBuffers().
2002-02-06fixed typo in depth_test_pixels(), should fix reported VTK failuresBrian Paul
2002-02-04Clean-up and remove dead code related to depth/stecil testing.Brian Paul
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.
