possible fix [#26930] Blender 2.57 Shuts down when trying to edit 3D text
can't test but this avoids using strncat which is giving problems.

=bmesh= fixed crasher

fixed a bug with normals

fixed idling problem

style changes & replace some memset's with zero initializers.

fix [#26937] Radio button text truncation should start at beginning of string
ensure start of text is always visible.

- also left in test for fix [#26933] which left it broken.
- quiet warning in AUD Py API.

=bmesh= merge from trunk at r36153

correct typo

float value reader in compositor backdrop (Alt + LMB Drag) should be 4 decimals like in image editor

fix [#26933] Render Crash with Decimate Modifier

no functional change, avoid making stack arrays for the purpose of indexing.

no functional change, avoid making a 4 pointer array just for an index lookup for tangents, orcos and normals.

fix [#26902] Raytracing black dots
derivatives from reflected duplis were not taking object instance transformation into account.

Fix #26932: When I enable multires, and start sculpting, some parts of the mesh just disappears.

Redraw issue was caused due to different redraw rectangles used for 3d view redraw and
gathering PBVH nodes to be re-drawed. I moved redraw rect expansion with rect from
previous step into sculpt_get_redraw_rect, so now redrawing works as it was planned
some commits ago -- redraw everything to which is inside currect rectangle and rectangle
from previous stroke step -- this still prevents artifact caused by fast strokes but
mesh doesn't disappear.

Brecht, Nicholas: it's the simpliest fix i could suggest atm. I've got some more
ideas with additional node flags, but it looked more complicated for me and
made code more difficult to understand. If you could see something better (like
revert all this redraw fixes for fast strokes) please tell me.

fix [#26931] Shift+Alt+RMB only selects loops, can't deselect them - 2.57 official
own fault with fix [#26885] for selected edges having de-selected verts in some cases.

fix for help menu docs linking to the wrong page, created a redirect so 2.57 release doesn't get 404's.

incorrect documentation spotted by macouno.

api to support different kinds of relative paths on export, including copying the files to a subdir.

A better fix than r36151 for the Grease Pencil drawing issues in the
Image Editor.

There's already a flag in use for tagging the "special drawing in
Image Editor" case, so make use of that now.
Most of the changes here are just whitespace tweaks...

=bmesh= fixed a few bugs in the uv editor
