  Log:
  Bugreport #4787 mentioned subpixel render issues, especially for small
  images (like used for rendering icons).
  
  When working during Orange on new render pipeline, I've left this topic
  alone for a while... subpixel precision testing is very time consuming and
  needs concentration for a while. :)
  
  This commit brings back precision as it was for 2.41. Below a short
  explanation of the solved issues.
  
  - the window matrix for rendering is kept constant during all OSA passes,
    this to ensure clipping happens for each pass identically.
  - a subpixel offset is only applied on filling in the z-buffer
  - this offset is inverse corrected for shadepixel code, only on 2 places
  
  Another nasty issue is that for filtered rendering (gauss etc), the tiles
  (or entire image) is temporally increased 2 pixel in size. This caused a
  'dark' (or sky color) edge on the rendering. During Orange that was solved
  with a hardcoded clipping offset value, which only corrected for larger
  pictures (like > 500 pixels in size).
  Now this clipping offset is correctly calculated, based on render size.
  
  Last issue: the view border in 3d window was calculated using integers,
  giving small errors in display too. Now it uses float, so visually the
  view border is more close to what a render shows.
