There really isn't any point. There is no resource savings, and we have to do gymnastics in the driver to make it work. There are also bad interactions with multisampling and OpenGL ES 3.0. In ES3, a multisample-to-singlesample blit must have identical source and destination format. This means a multisample RGBA8 to singlesample RGB8 (window) blit will generate an error. Also in ES3, RGB8 is not a renderable format. This means that the application CANNOT make an RGB8 multisample renderbuffer. As a result, if an application gets an RGB8 window and wants to do multisample FBO rendering, it will probably break. "Fixes" gles3conform framebuffer_blit_functionality_multisampled_to_singlesampled_blit test on RGB8 visuals. v2: Fix 'formats' array size. Suggested by Ken.

File: docs/README.WIN32 Last updated: 23 April 2011 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons osmesa mesagdi to build classic mesa Windows GDI drivers; or 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. 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.
