[GSOC] Tiled Rendering, ahunt, Weekly Report 06 / WK26

Hi All,

-- Tiled Rendering --
* Merged the LOK tiled rendering changes (+ gtktiledviewer) to master.
* Calc Tiled Rendering (now on feature/calctiledrendering2 after some
  more rebasing and squashing):
** Fixed Scaling of the grid, i.e. correct units (some TWIP/100th mm
   confusion).
** Scaling for the draw layer -- images now scaled and in correct place.
** Tried to get the column/rowbars synced up with the new scaling, not
   quite there yet (still digging into this).
** Fixed selection of cells to be rendered -- selecting too large a
   tile could result in cells beyond what would be visible on a normal
   screen not being rendered, we now adjust the "visible area" to
   ensure that all cells in a tile are rendered. (I.e. this happens if
   you have a large tile that is "zoomed out").

* Impress Remote:
** Got rid of a memory leak from 2 years ago (I was probably thinking
   in Java at the time).
** Added some "management" of remotes, i.e. the ability to remove
   authorised remotes again (previously allowing a remote meant it
   would be able to connect to LO forever, without any possibility of
   removing it).
** Misc. minor polishing:
*** Got rid of an annoying flickering of the dialog (changing
    visibility of controls that are overlayed over the current control
    in Paint() is a pretty bad idea it seems, as that results in a
    virtually infinite of Paint() calls, causing the flickering).
*** Pin entry now empty rather than pre-filled with 0.
*** Pin entry gets focus when remote selected.
* Some digging into firebird:
** Memory Mangement & References lessons...
