- Add blentranslation `BLT_*` module.
- moved & split `BLF_translation.h` into (`BLT_translation.h`, `BLT_lang.h`).
- moved `BLF_*_unifont` functions from `blf_translation.c` to new source file `blf_font_i18n.c`.
Steps to reproduce were: startup.blend, move any object, delete active scene (nothing happens), undo (nothing happens), second undo is needed to revert object transformation
The issue was caused by the following construction:
def = env['SOMETHING']
defs.append('SOMETHING_MORE')
Since first assignment was actually referencing environment option it was totally
polluted hawing weird and wonderful side effects on all other areas of Blender.
This resolves a problem where selected items edited for multi-value-editig
could include objects not in any visible views (unlocked layers, local view... etc).
Moral of the story: Make sure that size_t is used whenever pointer
arithmetic is involved. For images, that basically means whenever any
squared dimensions are involved. Casting an operand to size_t early in
the operation is usually sufficient to force the entire operation to
size_t.
There might still be places lurking where we don't support this
correctly. This has been tested with render pipeline, quite a few image
functions (meaning we can paint on such images now, albeit somewhat
slowly ;) ) and export to jpeg. Too many places in code to check so I
guess we'll be handling cases as they come.
Don't try this at home unless you have an immense ammount of RAM.
First GPixel render of suzanne in the multiverse can be found here:
http://download.blender.org/demo/test/suzanne-billion-pixel.jpg
Can be viewed from blender (takes about 3.3 GB after loading but may
take more during loading so 8GB might be more safe to try this).
In this case we can calculate an offset without worrying about
perspective correction. Unfortunately if looking from a camera we still
have depth issues here. There's no really general case that can fix this
so I'm leaving this as is.
Issue is zfighting with wire of mesh when parts of the mesh are close
together. We can make this slightly better by reducing the offset,
however this offset is calculated pre-perspective division and can vary
greatly with distance. Correct approach would be using polygon offset,
however we draw mesh wireframes as lines, (not polygons with polygon
mode line) so this approach will not work.
Alternatively, we could set an offset in a shader, however we don't have
code for that either.
Tried a couple of things to trigger an update/redraw for the exact right
moment (sending azone update event, timer, delayed redraw, etc) but this
seems to work rock solid without being *that* ugly.
Basically, blender adds a few metadata fields to images when
we render an image. Those metadata can now be viewed in the
image editor.
Also, made sure metadata are available when we write imbufs
to disc with "Save As". There may be more cases here that need
fixing, but this means that loading an image with metadata
will now properly preserve them in blender.

Missing Bits
============
First rule of Multi-View bug report: If something is not working as it should *when Views is off* this is a severe bug, do mention this in the report.
Second rule is, if something works *when Views is off* but doesn't (or crashes) when *Views is on*, this is a important bug. Do mention this in the report.
Everything else is likely small todos, and may wait until we are sure none of the above is happening.
Apart from that there are those known issues:
* Compositor Image Node poorly working for Multi-View OpenEXR
(this was working prefectly before the 'Use Multi-View' functionality)
* Selecting camera from Multi-View when looking from camera is problematic
* Animation Playback (ctrl+F11) doesn't support stereo formats
* Wrong filepath when trying to play back animated scene
* Viewport Rendering doesn't support Multi-View
* Overscan Rendering
* Fullscreen display modes need to warn the user
* Object copy should be aware of views suffix

range and extra frames.
Issue here is that the movie backend would unconditionally use the start
frame of the scene instead of the preview frame. Solved by passing an
explicit "preview" argument.
Strictly speaking, the preview argument is part of the renderdata
struct, that is also passed to the code, but when rendering the final
result we want to unconditionally render the full range regardless of
the preview setting of the render structure.
However, OpenGL rendering does use the preview range so we need to
account for that when making those exports.
This is also a nice chance to correct the filenames, which still used
the full range.
ED_area_data_swap would put the screen in an invalid state and crash.
(SpaceLink.spacetype didn't match ScrArea.type)
However behavior is still odd in the instance of the report.
