From a35f6bb207efe3c959bbd16a37f2049e5aceeea9 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Fri, 17 Jul 2009 03:30:29 -0400 Subject: DRI2: add SwapBuffers support Support the new DRI2 protocol request, DRI2SwapBuffers, in both direct and indirect rendering context. This request allows the display server to optimize back->front swaps (e.g. through page flipping) and allows us to more easily support other GLX features like swap interval and the OML sync extension in DRI2.

Everybody is using the C99's integer types. Everybody except Microsoft, which in turns means everybody is including their own definitions of C99 integer types for MSVC, causing duplicate definitions when linking two projects. This is the case of building Gallium and LLVM with MSVC. Shipping alternative stdint.h and stdbool.h headers for MSVC allows us to share a single definition.
