Ton Roosendaal e47137ff42 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.

Welcome to the fun world of open source.

For instructions on building and installing Blender, please see the file named
INSTALL.


---------------------.Blanguages and the .blender directory---------------------

The .blender directory holds various data files for Blender.
In the 2.28a release those are the .Blanguages file containing a list of
translations, the translations themselves and a default ttf font.

Blender checks for the presence of this directory in several locations:
	- the current directory
	- your home directory
	- On OSX, the blender bundle is also checked 
	- On Windows, the installation dir is checked.

If you get a 'File ".Blanguages" not found' warning, try to copy the .blender
dir to one of these locations (your home directory being recommended).
