Issue was caused by left boolean operand consist of several intersecting manifolds
which make Carve triangulator confused and which can't be resolved in general case.
Added mesh pre-processing before actual applying boolean operator on it. This
preprocessing applies union operation on intersecting manifolds of the same object
so intersection edge loop with second object wouldn't confuse tesselator and correct
result would be returned.
Detecting of intersecting manifolds is based on AABB intersection check which leads
to some extra union operation called, but it's possible to speed things up from
Carve side so union operation of two not intersecting meshes would work faster.
Additional condition for running union for manifold is this manifolds intersects
AABB of second operand, so mesh topology wouldn't be changed at all in areas
where there's definitely no intersection between operands. It might be improved
so only manifolds which actually intersects second operand would be joined
together, but it'll slow things down a bit and prefer to do it only if it'll
be really a problem.
Additional change is fixed memory leak when boolean operation fails to run -
it was missed "delete" call if exception happens in Carve library.
From side effects of this change might be named boolean operation between
suzanne and another object: suzanne is consist of three intersecting open
manifolds, so this new meshes preprocessing leads to missed eyes in result
because of failure of merging two open manifolds. Don't think making suzanne
work for all setups should really be a goal, it's a bit crappy mesh for CSG
algorithms.

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

* Use full width for the world sample as lamp properties

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.

By default lighting from the world is computed solely with indirect light
sampling. However for more complex environment maps this can be too noisy, as
sampling the BSDF may not easily find the highlights in the environment map
image. By enabling this option, the world background will be sampled as a lamp,
with lighter parts automatically given more samples.
Map Resolution specifies the size of the importance map (res x res). Before
rendering starts, an importance map is generated by "baking" a grayscale image
from the world shader. This will then be used to determine which parts of the
background are light and so should receive more samples than darker parts.
Higher resolutions will result in more accurate sampling but take more setup
time and memory.

Tablet mode (stylus/eraser) wasn't properly set when pen was already hovering over
tablet surface when opening blender (i.e. in cases when blender was opened using
stylus tap).
Issue resolved by setting tablet mode when handling tablet's motion event too.

Error was caused by boost library (which doesn't seem to be working with Cycles too
when compiling with mingw). Switched mingw to use TR1 unordered collections. Also,
there was re-declaration of strcasecmp when mingw is used.
Additional changes are related on using own process spawning when BF_TOOLSET is set to
mingw. Seems to be working fine now (i've got too long command line error) and no
warning are supressing now (as it was told in comment for commented own process spawning).

==================================
Merging Carve library integration project into the trunk.
This commit switches Boolean modifier to another library which handles
mesh boolean operations in much stable and faster way, resolving old
well-known limitations of intern boolop library.
Carve is integrating as alternative interface for boolop library and
which makes it totally transparent for blender sources to switch between
old-fashioned boolop and new Carve backends.
Detailed changes in this commit:
- Integrated needed subset of Carve library sources into extern/
Added script for re-bundling it (currently works only if repo
was cloned by git-svn).
- Added BOP_CarveInterface for boolop library which can be used by
Boolean modifier.
- Carve backend is enabled by default, can be disabled by WITH_BF_CARVE
SCons option and WITH_CARVE CMake option.
- If Boost library is found in build environment it'll be used for
unordered collections. If Boost isn't found, it'll fallback to TR1
implementation for GCC compilers. Boost is obligatory if MSVC is used.
Tested on Linux 64bit and Windows 7 64bit.
NOTE: behavior of flat objects was changed. E.g. Plane-Sphere now gives
plane with circle hole, not plane with semisphere. Don't think
it's really issue because it's not actually defined behavior in
such situations and both of ways might be useful. Since it's
only known "regression" think it's OK to deal with it.
Details are there http://wiki.blender.org/index.php/User:Nazg-gul/CarveBooleans

- Campbell Barton: help in project development, review tests.
- Tobias Sargeant: author of Carve library, help in resolving some
merge stoppers, bug fixing.

disk to be reused by the next render.
This is useful for rendering animations where only the camera or materials change.
Note that saving the BVH to disk only to be removed for the next frame is slower
if this is not the case and the meshes do actually change.
For a render, it will save bvh files to the cache user directory, and remove all
cache files from other renders. The files are named using a MD5 hash based on the
mesh, to verify if the meshes are still the same.

Notes:
======
* we replaced fullscreen by playerflag in DNA_scene.types.h. So no doversion here, I think this is a small reversion can't see any potential problem in forcuing users to re-check fullscreen. If the file is really old (<250) it will doversion though;
* (for after commit) it would be nice to gray out the width/height when desktop=True
* for a rainy day: it would be nice to have other ghost modes (e.g. screensaver) to support desktop + MSAA as well. It's not a huge deal given that I don't even know if anything else work (apart from windowed, fullscreen and embed) but it doesn't hurt to have it updated as well.
* there is something strange with outliner. I think space_outliner merge-info is not in sync with the ^/ folder. It's probably a wrong merge early in cucumber.
Commit Logs:
===========
# 40845 by dfelinto
remove desktop and fullscreen properties. They are both part of playerflag now
also I removed the fullscreen from the DNA completely. I don't think we need doversion that..
#39045 by kupoman
The Desktop option is now greyed out when fullscreen is not checked rather than disappearing from the UI completely.
#38973 by kupoman
Adding a checkbox to the UI to allow the full screen Blender Player to use the current desktop resolution instead of the resolution setting.
#38970 by kupoman
Multisampling now works in a fullscreen Blender Player.
#38968 by moguri
Committing a patch from Mitchell Stokes (Moguri) to include a setting in the UI for the Blenderplayer multisampling.

The rendering device is now set in User Preferences > System, where you can
choose between OpenCL/CUDA and devices. Per scene you can then still choose
to use CPU or GPU rendering.
Load balancing still needs to be improved, now it just splits the entire
render in two, that will be done in a separate commit.

This patch adds a new remeshing modifier. The algorithm is based on
the paper "Dual Contouring of Hermite Data", and the implementation
was contributed to Blender by Dr. Tao Ju.
The contributed code is in intern/dualcon, and was modified to compile
under gcc and work on 64-bit systems. Files not needed for Blender
were removed and a small C wrapper was added in order to interface it
with Blender. The rest of the patch is just standard modifier stuff.

The remesh icon was contributed by Zafio:
