Alan Coopersmith 6c06c268ad Skip damage calls if DamageCreate fails in exa functions 
Fixes parfait errors such as:
   Null pointer dereference (CWE 476): Write to null pointer pDamage
        at line 1833 of miext/damage/damage.c in function 'DamageRegister'.
          Function DamageCreate may return constant 'NULL' at line 1775,
              called at line 232 of exa/exa_migration_mixed.c
              in function 'exaPrepareAccessReg_mixed'.
          Constant 'NULL' passed into function DamageRegister,
              argument pDamage, from call at line 237.
          Null pointer introduced at line 1775 of miext/damage/damage.c
              in function 'DamageCreate'.
   Null pointer dereference (CWE 476): Write to null pointer pDamage
        at line 1833 of miext/damage/damage.c in function 'DamageRegister'.
          Function DamageCreate may return constant 'NULL' at line 1775,
              called at line 104 of exa/exa_mixed.c
              in function 'exaCreatePixmap_mixed'.
          Constant 'NULL' passed into function DamageRegister,
              argument pDamage, from call at line 109.
          Null pointer introduced at line 1775 of miext/damage/damage.c
              in function 'DamageCreate'.

Checks are similar to handling results of other calls to DamageCreate.

					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:

All questions regarding this software should be directed at the
Xorg mailing list:
