Nicer handling of undefined node, tree and socket types.

When nodes are loaded from a .blend file they can potentially have undefined types. This can happen if a type has been deprecated and removed, or if node types were defined in a python script that has not been loaded correctly. Previously all such nodes would automatically be removed from a node tree, assuming that their types were deprecated and no longer in use (more commonly caused by loading new nodes in an older Blender version). Due to the possibility of dynamic registration it is no longer feasible to simply delete such nodes.

Display and handling of node trees was simply disabled before this patch, so that a node tree where any node or socket type was undefined would not be displayed at all. To give more information and avoid problems caused by necessary checks for the typeinfo pointer, there is now a 'Undefined' fallback type for trees, nodes and sockets. These types are used as placeholders in case the real type is not registered and can provide useful visual feedback on undefined nodes.

Fix regression in viewport background image transparency

Was caused by recent changes to automatically switch between
glaDrawPixelsTex and glaDrawPixelsSafe depending on resolution.

glaDrawPixelsSafe could not be sued for viewport because it'll
miss alpha transparency.

Fix: Clamp alpha to 1.0 or adding alpha in paint creates "isolines" due
to integer overflow. One of the beautiful bugs that is sad to see fixed.

Also remove unused timer variable

UI / Node Editor:
* Align Render Layer menu and Render button in "Render Layers" node.
This looks better and the settings belong together as well.

Fix for GLSL shader nodes when using Cycles nodes with shader sockets. These did not get a stack index assigned, but for GLSL they are simply replaced by colors.

OSX/pen: change sensivity graduation to a good value found with Sebastian and remove debug print

OSX/pen: change sensivity graduation so we don't get maximum too early and have more feeling

add BLI_rcti,f_recenter()
fix for uninitialized variable use in radial_control_get_properties() and bad cast in bpy api's foreach_parse_args()

Fixes for context updates of the node editor:
* If the node tree can be updated from context (tree has get_from_context callback defined), reset the pointers first to clear the editor path if no tree can be found.
* Stupid mistake: snode->from != snode->from is always false.
* Shader nodes context update: set the 'from' pointer to the active object, even if it doesn't have a material or node tree.

More i18n tools cleanup. Also do not import nl in trunk currently (void translation)!

quiet warnings by making undeclared vars static

Fix for shader node sockets not displaying the name when unconnected. Default button draw implementation for node sockets should be to display just the name label.

Use checker backdrop for footage with alpha channel in clip editor

Also use glaDrawPixelsAuto as a fallback method. Hopefully it'll
make using 2D textures for frames higher resolution than
GL_MAX_TEXTURE_SIZE.

Some renaming/cleanup in i18n tools.

Added alpha output to movie clip compositor node

Pretty much straightforward change, made in the same way as
texture input node.

Shall not be any regressions or crashes when mixing usage
of 2.66 and current trunk.

BGE: Adding docs for bge.logic.getProfileInfo().

BGE: Adding a getProfileInfo() function to bge.logic. This function returns a Python dictionary with the same information as the on screen profiler.

fix for assert(), were not enough mathutils slots.

bge bugfix: [#34677] Setting Boolean property on KX_GameObject creates Int type
we need to check for booleans before testing for longs.

fix for some errors.
