Fix for cmake for recent mingw png lib move.

MinGW png libs
* Moved to gcc/png in the libs dir.

remove unneeded NULL check in ui_searchbox_create() which confuses static checkers since the values used later.

remove windows only benchmark functions, use PIL_time.h's TIMEIT macros instead.

Minor tweaking to WeightVGProximity modifier code (not really usefull currently, but mandatory for other future changes�?�)

Object tracking: scale object itself when setting scale in object tracking mode

Also fixed incorrect poll functions which didn't check active object when orienting object.

Object tracking: forgot to initialize inverted matrix for object solver constraint

Removed buttons in node headers for hiding unused sockets and for hiding the (non-socket) option buttons. These are rarely used buttons that only complicate the UI. Alternatively these operators can still be accessed in the Node menu of the node editor window, "Toggle Hidden Node Sockets" and "Toggle Node Options" respectively.

Generalized node groups for Cycles.

This allows group nodes inside other group nodes in cycles and makes the
code more generic for all possible cases, like direct group
input-to-output links and unused group sockets.

Previous code tried to connect external nodes and internal group sockets
by following links until a "real" node input/output. This quickly
becomes complicated in corner cases as described above and can lead to
unexpected behavior when the group socket is of a different type than
the internal/external sockets, but that conversion is skipped.

The new code uses the concept of "proxy nodes" similar to what the new
compositor does. Each group socket is replaced with a proxy node with a
single input and output, to which other nodes in the same tree and
internal nodes can link to. After all groups have been expanded in the
graph, these proxy nodes are removed again, adding converter nodes if
necessary.

cleanup of weight paint color setting code, no functional changes

Fix for toggle buttons in node headers.

The buttons for "hiding" (collapsing) a node, hiding unlinked sockets, additional options, the preview and for opening a node group were all using a custom mouse test function, which was broken. They now use actual buttons instead of just displaying icons. Before executing the respective operators the button's node has to be selected and activated, so the buttons use an intermediate handle function, which selects the node and then calls the operator.

- remove rna access to deprecated sequencer attributes x/y offset & zoom.
- Object.to_mesh was still using deprecated colbits variable (object material wouldnt work for any material after 16)
- dont set colbits when setting material slot anymore.

formatting edits in py api, no functional changes

Support for arbitrary sized vectors - (was limited by 2-4 previously)

patch http://codereview.appspot.com/5482043
from Andrew Hale

* Text from the submission *

This patch adds the ability to use arbitrary sized vectors from mathutils.
Currently vectors are only of size 2, 3 or 4 since they are generally restricted
to geometric applications. However, we can use arbitrary sized vectors for
efficient calculations and data manipulation.

Merged changes in the trunk up to revision 42692.

bugfix: [#29486] 2D filters make scene disappear when wire material used - patch by Juha Mäki-Kanto
when last drawn material is wire it will not set back to face drawing.

Added SVertex::curvatures() in the Python API to retrieve curvature
information at a given SVertex.

Quite some compiler warnings...

better to generate the library string always because it could lead to null pointer dereferences. I don't have a non-shader system to check so skipping the conditional just to be safe

move GPU_code_generate_glsl_lib to GPU_extensions_init. This makes more sense as we cleanup the library string in GPU_extensions_exit. Thanks to Mitchel Stokes for reporting and proposing this
