Cycles Textures:
* Remove the "Use nodes" button, the TextureOutput node was never ported to trunk from the cycles branch.

Cycles UI:
* Use full width for the world sample as lamp properties

Ocean Modifier UI fixes:
* Modifier Icon was missing in the outliner
* Fluid icon was used in the rna struct, fixed

Note: Ocean uses the Wave modifier icon atm, if we find a better one, this can be changed.

dissable double re-tesselation when entering editmode.

dissable editmode tesselation calculation on exiting editmode, the mesh conversion function does this.

disable re-tesselation for modifiers that use bmesh, array/bevel/edge split - were tesselating 2 times and didnt need to.
also comment array modifier from flushing selection flags.

Committing patch "[#27676] Change window size/resolution in realtime" by me.

Description:
This patch allows the user to change the size of the window (or the resolution in fullscreen mode) using the new bge.render.setWindowSize() method. This only works in the Blenderplayer since it doesn't make a whole lot of sense for the embedded player.

svn merge ^/trunk/blender -r43611:43616

Merged with trunk (-r43609:43611): updated modifier preview.

Noted preview code for DynamicPaint is currently disabled, will see if I can re-enable itâ?¦

restrict stitching of same island uvs to only midpoint, without snapping case

minor edit for operator error macro so it can return different values.

error in outliner parent patch - was using set string on an enum property.

minor header tidy up

svn merge ^/trunk/blender -r43564:43609

Add weight preview to WeightVG modifiers, and first, simple/basic refactor of how modifiers can generate preview.

User side:
* Preview for DynamicPaint should keep the same behavior (for now). Weight preview should be somawhat quicker, though.
* Preview for WeightVG modifiers is only active in WeightPaint mode, and if the affected vgroup is the active one.
* Last active preview modifier in stack wins!

Note: that modifier preview topic is yet to be further refined, quite raw/incomplete for now.

Dev side:
* In draw code, renamed DRAW_DYNAMIC_PAINT_PREVIEW flag to DRAW_MODIFIERS_PREVIEW
* Removed use of MOD_DPAINT_PREVIEW_READY in DynamicPaint code (seems unecessary, and if it was, should be of more general scope).
* Added eModifierTypeFlag_UsesPreview to ModifierTypeFlag, for modifiers that can generate some preview data.
* Added three new modifier funcs, to handle preview modifiers in draw code / mod stack.
* For weights preview: added the generic DM_update_weight_mcol func, which can update WEIGHT_MCOL layer with either a given array of weights (currently used by DynamicPaint only), or from current active vgroup(s).

So now, draw code is fully generic (i.e. no more modifier-type checking in it). Mod stack code is generic to some extent, but will need more work.

Quiet warnings in text editor

use inline BLI_math functions for dot product and length calculation.

Fix for the Sculpt UI (revert part of 43535 by nicholasbishop)
* Such labels like for "use_space_atten" should not be in the UI, thats too overkill. Toolbar is meant to be small in size.

Fix #29935: missing cycles update/crash when removing world datablock form scene.

Fix missing shadows with cycles world sample as lamp option, my mistake in
tweaking patch.
