Paints with textures, using a temporary buffer for overlapping copies Performs CPU to GPU transfers for pixmaps in memory. Accelerates copy plane when both objects are in the GPU. Includes copy_window acceleration too. v2: Use NV_texture_barrier for non-overlapping copies within the same drawable v3: Switch to glamor_make_current v4: Do overlap check on the bounding box of the region rather than on individual boxes v5: Use Eric Anholt's re-written comments which provide a more accurate description of the code v6: Use floating point uniform for copy plane bit multiplier. This avoids an int to float conversion in the copy plane fragment shader. Use round() instead of adding 0.5 in copy plane. round() and +0.5 end up generating equivalent code, and performance measurements confirm that they are the same speed. Round() is a bit clearer though, so we'll use it. Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Eric Anholt <eric@anholt.net> Reviewed-by: Markus Wick <markus@selfnet.de> |

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: http://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: http://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver http://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: http://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: http://wiki.x.org/wiki/GitPage
