Composite's automatic redirection is a more general mechanism than the ad-hoc BS machinery, so it's much prettier to implement the one in terms of the other. Composite now wraps ChangeWindowAttributes and activates automatic redirection for windows with backing store requested. The old backing store infrastructure is completely gutted: ABI-visible structures retain the function pointers, but they never get called, and all the open-coded conditionals throughout the DIX layer to implement BS are gone. Note that this is still not a strictly complete implementation of backing store, since Composite will throw the bits away on unmap and therefore WhenMapped and Always hints are equivalent. |

This directory contains a port of the XDarwin code to the modular X.org codebase to be compiled on Darwin/OS X; this would not have been possible without the help of Torrey Lyons and Peter O'Gorman, to whom I am grateful for their patches, time and moral support. The server builds 4 targets: * XDarwin: this server runs on Darwin systems without Quartz (i.e. non-OS X); it has not been well-tested. * XDarwinApp: this builds XDarwin.app, which is a full X server using Quartz. It has loadable module support for AGL and CGL, and well as fullscreen and rootless support. * Xquartz: this server runs on Quartz-based systems, and is meant to work with X11.app * x11app: this builds a version of Apple's X11.app using patches by Torrey Lyons; most, but not all, functionality of Apple's original X11.app is present in this release. Known issues: * AGL and CGL support for 3D indirect acceleration does not work; indirect.c has been rewritten, but not yet integrated into this source tree. * Fullscreen mode does not work; I don't know why. * Some features in X11.app are not yet implemented; these are marked with #ifdef DARWIN_DDX_MISSING in the code. * The build system code could probably be cleaned up slightly. Any patches or code contributions would be most welcome and may be sent to me at bbyer@apple.com.
