2):
MIT-BIG-REQUESTS
Permits client requests over 256 Kb, necessary to draw complex images.
MIT-SHM
Offers shared memory for local communication of images.
Composite
Enables off-screen rendering of windows, which are then combined (composited)
into the final screen image by hardware under control of a compositing
manager. This is usually integrated into the window manager. During composition,
images can be distorted, blended, and resized, so the extension provides an
easy way to add drop shadows, window transparency, icons, and thumbnails
that are ???live,??? smooth window resizing, and many other 2D and 3D visual
effects.
DAMAGE
Informs a client when one part of the display has been updated. Reduces unnecessary
drawing and improves the efficiency of applications such as VNC (Section
14.1).
1.15
1.15 Server Extensions 23
DPMS
Displays Power Management Signalling. Enables the X server to reduce monitor
power consumption when not in use (Section 3.11).
GLX
OpenGL extension for X11. Enables clients to send OpenGL 3D commands to
the X server, which then passes them on to 3D video hardware (or performs the
3D operations in software if necessary??”which is very slow!).
LBX
Low-Bandwidth X.
