2006-10-13remove needless conditionBrian Paul
2006-10-13Consolidate, move, fix code related to color index and stencil image transferBrian Paul
operations (shift, offset, table lookup, etc).
2006-10-13In _mesa_pack_rgba_span_float() we don't need to make a temporary copy ofBrian Paul
incoming colors when applying pixel transfer ops. In all cases, the caller either indicates there's no pixel transfer ops, or the incoming colors are coming from temporary storage already and can be safely modified.

2006-10-13removed obsolete _mesa_pack_rgba_span_chan()Brian Paul
2006-10-12don't use temp storage in _mesa_convert_colors() when possibleBrian Paul
2006-10-11Added _mesa_convert_colors().Brian Paul
_mesa_clip_drawpixels() now handles Pixel.ZoomY==-1.
2006-09-11undo some accidental changes in _mesa_is_legal_format_and_type()Brian Paul
2006-09-10Redefine the BYTE_TO_FLOAT() and SHORT_TO_FLOAT() macros to avoid problemsBrian Paul
converting 0 to exactly 0.0 This goes against the OpenGL spec (see table 2.6) but solves problems when doing byte -> float -> ubyte conversion for particular texture formats.

2006-05-05check for float->uint overflow in _mesa_unpack_depth_span()Brian Paul

2005-11-12Added OSMesaColorClamp(), bug 4917Brian Paul
2005-11-09Bug 4996.Brian Paul
Replace use of FLOAT_TO_USHORT with either CLAMPED_FLOAT_TO_USHORT or UNCLAMPED_FLOAT_TO_USHORT. Same should be done for UBYTE, UINT, etc.
2005-10-01added _mesa_pack_depth_stencil_span()Brian Paul
2005-09-28Initial work for GL_EXT_packed_depth_stencil extension.Brian Paul
glReadPixels done, glDrawPixels mostly done.
2005-09-06remove DEFARRAY, CHECKARRAY stuffBrian Paul
2004-12-03silence a variety of warnings found with g++ 3.4.2Brian Paul
2004-11-10GL_(UN)PACK_SKIP_IMAGES should only be applied to 3D texture pack/unpackingBrian Paul
and ignored for 1D and 2D images. Need to pass in image dimensions (1,2,3) to the _mesa_image_address() function. This change gets propogated to some other routines. Also added new _mesa_image_address[123]d() convenience functions.
2004-11-09added a comment and assertion in _mesa_clip_drawpixels() for PixelZoomBrian Paul
2004-11-09added _mesa_clip_drawpixels() and _mesa_clip_readpixels()Brian Paul
2004-10-31Use the _mesa_scale_and_bias_rgba() function in the convolution functions.Brian Paul
Minor clean-ups.

the 1.5 spec
2004-05-12GL_BGR can't be used with the packed types, according to the GL spec. ↵Brian Paul
Enforce such.
2004-05-12some component ordering bugs in extract_float_rgba()Brian Paul
2004-04-22New glTexImage code.Brian Paul
The gl_texture_format struct now has a StoreTexImageFunc that's called by glTex[Sub]Image[123]D to convert the user's texture data into the specific texture format layout. Now it's much easier to add new texture formats (like the 16/32-bit floating point formats). The texutil.[ch] and texutil_tmp.h files are obsolete.
2004-03-13Implementation of GL_EXT_pixel_buffer_object extension.Brian Paul
Note: extension may not be finalized yet - subject to change! Note: implementation not fully suitable for h/w implementation yet.
2004-02-28Remove clamp parameter from _mesa_unpack_color_span_float(). Pass theBrian Paul
IMAGE_CLAMP_BIT if needed. Added ClampVertexColors and ClampFragmentColors to GLcontext in anticipation of upcoming extensions (not fully used yet).

Moved type conversion and interpolation macros into macros.h Updated all the files that used to include mmath.h
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.

2002-03-19Use 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.
