The vbo_save_vertex_list structure records one or more glBegin/End primitives which all have the same vertex format. To draw these primitives, we setup the vertex array state, then issue the drawing command. Before, the 'start' vertex was typically zero and we used the vertex array pointer to indicate where the vertex data starts. This patch checks if the vertex buffer offset is an exact multiple of the vertex size. If so, that means we can use zero-based vertex array pointers and use the draw's start value to indicate where the vertex data starts. This means a series of display list drawing commands may have identical vertex array state. This will get filtered out by the Gallium CSO module so we can issue a tight series of drawing commands without state changes to the device. Note that this also works for a series of glCallList commands (not just one list that contains multiple glBegin/End pairs). No Piglit or conform changes. v2: minor fixes suggested by Ian.

File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. - install python 2.7 - install scons (latest) - install mingw, flex, and bison - install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe - install git - download mesa from git see https://www.mesa3d.org/repository.html - run scons General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
