+Filter Manager service calls:
+
+Service_FilterManagerInstalled
+------------------------------
+ in     R0 = Version number of Filter Manager *100, ie. 1.23 => 123
+        R1 = Service_FilterManagerInstalled
+ out    all must be preserved, must never be claimed
+
+This service call is broadcast to allow modules that install a Filter
+to be reinstalled when the filter manager is reloaded / re-inited.
+
+The SWI is issued on a callback, so the SWI interface is valid for
+registering filters.
+
+
+Service_FilterManagerDying
+--------------------------
+ in     R1 = Service_FilterManagerDying
+ out    all must be preserved, must never be claimed
+
+This is broadcast when the filter manager has unlinked all filters from
+its active lists (just before the module dies) to allow the filter owners
+to tidy any internal state.
+
+
+Filter manager SWIs:
+
+
+Filter_RegisterPreFilter
+
+ Add a new pre filter to the list of pre filters.
+
+ Entry:
+        R0 - Pointer to 0 terminated filter name. 
+        R1 - Addresss of filter.
+        R2 - Value to be passed in R12.
+        R3 - Task handle of task to which filter is applied.
+             or 0 for all tasks.
+
+ Exit:
+        Registers preserved.
+
+        The address pointed to by R1 will be called whenever the task who's
+handle is passed in R3 calls Wimp_Poll with R12 equal to the value of R2
+when this SWI is called.
+
+                         
+        The routine pointed to by R1 will be called with:
+
+        R0 =  Event mask as passed to Wimp_Poll
+        R1 -> Event block as passed to Wimp_Poll
+        R2 = Task handle of task that called Wimp_Poll.  
+
+        On Exit:
+
+        It may clear bits in r0 to provide a new event mask.
+
+        It must preserve all other registers.
+
+
+
+Filter_RegisterPostFilter
+
+ Add a new post filter to the list of post filters.
+
+ Entry:
+        R0 - Pointer to 0 terminated filter name. 
+        R1 - Addresss of filter.
+        R2 - Value to be passed in R12.
+        R3 - Task handle of task to which filter is applied.
+             or 0 for all tasks.
+        R4 - Event mask ( 1 bit masks the event out as for Wimp_Poll).
+
+ Exit:
+        Registers preserved.
+
+  
+        The address pointed to by R1 will be called whenever the Wimp is
+about to return to the task who's handle is passed in R3 from Wimp_Poll with
+R12 equal to the value of R2 when this SWI is called.
+
+        On entry to the routine pointed to by R1:
+
+        R0 - Event reason code (as from Wimp Poll)
+        R1 -> User's event buffer.
+        R2 = Task handle for task to which the return is made.
+        Task paged in.
+
+        On Exit:
+
+        The routine may modify the reason code in r0 and the contents of the 
+        buffer pointed to by R1 to provide a new event.
+
+        It must preserve R1 and R2.
+                                          
+
+
+
+
+ Filter_DeRegisterPreFilter
+
+ Remove a pre filter from the list of pre filters.
+
+ Entry:
+        R0 - Pointer to 0 terminated filter name. 
+        R1 - Addresss of filter.
+        R2 - Value to be passed in R12.
+        R3 - Task handle of task to which filter was applied.
+
+        All must be the same as those passed to RegisterPreFilter
+ Exit:
+        Registers preserved.
+        Filter de-registered.
+
+
+ Filter_DeRegisterPostFilter
+
+ Remove a pre filter from the list of pre filters.
+
+ Entry:
+        R0 - Pointer to 0 terminated filter name. 
+        R1 - Addresss of filter.
+        R2 - Value to be passed in R12.
+        R3 - Task handle of task to which filter was applied.
+
+        All must be the same as those passed to RegisterPreFilter
+ Exit:

+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions

+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,

+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
