When layout has only small buttons (buttons with icon and without label)
its size should be fixed. Code was modified to be able to add a new UI_ITEM_MIN
flag which indicates that the layout has only small fixed-width buttons.

Enum properties with icon only flag should use minimum/fixed width in expanded layouts (alignment=UI_LAYOUT_ALIGN_EXPAND).
Differential Revision: https://developer.blender.org/D2415 by @raa (only made some really minor corrections)
//ui_item_enum_expand// function replaces all pie menu's sub-layouts with radial layout. It should replace only root layout.
To reproduce the issue paste the code in Blender's text editor and press Run Script button.
```
import bpy
class VIEW3D_PIE_template(bpy.types.Menu):
bl_label = "Select Mode"
def draw(self, context):
layout = self.layout.menu_pie()
layout.column().prop(
context.scene.render.image_settings, "color_mode", expand=True)
def register():
bpy.utils.register_class(VIEW3D_PIE_template)
def unregister():
bpy.utils.unregister_class(VIEW3D_PIE_template)
if __name__ == "__main__":
register()
bpy.ops.wm.call_menu_pie(name="VIEW3D_PIE_template")
```

Column flow layout was abuse ui_item_fit in a weird way, which was
broken for last column items.
Now rather use own code, which basically spread available width as
equally as possible between all columns.
Now a 'More' item is added to the pie when there are too many items. It opens a sub-pie that contains the remaining items.
Note that this only touches operator-enum pies (like the object mode pie is), it is not a complete support for pies with more than 8 items. For this further design and code work would be needed, but this is too urgent to wait for that.
This is a better fix for T46973, should definitely be applied for 2.77 release.
Patch D1800 by myself with some edits by @campbellbarton, thanks!
To ensure all items of a pie are always at the same position, invisible dummy buttons were added for unavailable items. This caused mainly two issues: Command line printed warning because of the > 8 elements, and some modes weren't visible in some cases ('Object Mode' entry was missing in stroke edit mode).
To solve this nicely, we had to support > 8 items per pie. Will look into that this week, but for now, drawing dummy buttons is disabled.
From a user POV this has two ugly consequences: 1. While this temporary workaround is used, *some* pie items are positioned differently than before, 2. The 'Edit Strokes' mode entry might change its position depending on the amount of available modes.
This new code fixes a tons of issues with previous one, which basically was epic-failing
in many non-basic cases (especially mixed columns and rows with column-dominant layout).
It basically no more relies over order of buttons declaration in the uiBlock, instead it
finds and stores spatial neighbors and uses that data to compute needed stitching.
See code comments for details.
New code seems to be roughly ten times slower than old one (for complex grouped layouts),
that is, about a few microsecconds per alignment group - this remains reasonable.
Also, ui-align code becomming rather big in itself, it was separated in
own new `interface_align.c` file.

- 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`.
We already had that for global keymaps (used e.g. to generate shortcuts for menu entries),
but this wasn’t possible for modal keymaps yet (e.g. help message in header during
transforms and other modal operation).
This commit only adds needing background code, it does not change anything from user PoV.
Modal operators will be updated to use it in comming weeks.
Thanks to Campbell for revisions & suggestions. :)

This will print a warning and users will get overlap of pie buttons, but
it should be quick paper over the cracks and at least should keep
blender working until a more complete fix is coded.
