This fixes:
[#8521] Sequencer: numpad zoom is inconsistent

oddly enough this printf was the only problem compiling blender with GCC 4.3

Delta Loc/Rot/Scale Ipo curve are now supporting in the BGE with the following limitations:

1. All Ipo channels are now independent.
In Blender 2.45, all 3 Loc Ipo channels were automatically set
together. For example, having just a LocX Ipo channel was sufficient
to fix the X, Y and Z coordinates, with the Y and Z value taken
from the object original Y and Z location in Blender. The same
was true for the 3 Rot and the 3 Scale Ipo channels: the missing
channels were assumed to have constant value taken from the object
original orientation/scale in Blender.
With this patch, all Ipo channels are now independent.
THIS WILL CREATE BACKWARD COMPATIBILITY PROBLEM if you omit to
define the 3 channels of a same type together in your Blend file:
the undefined Loc, Rot, Scale coordinates of the object will
be influenced by the parent/spawner Loc/Rot/Scale in case the
object is a child or dynamically created.

2. Delta Loc, Rot, Scale are now supported with the following
limitations:
- The delta Loc/Rot Ipo modify the object global (NOT local)
location/orientation
- The delta Scale change the object local scale
- The delta Ipo curves are relative to the object starting
Loc/Rot/Scale when the Ipo was first activated; after that, the
delta Ipo becomes global. This means that the object will return
to this initial Loc/Rot/Scale when you later restart the Ipo
curve, even if you had changed the object Loc/Rot/Scale in the
meantime. Of course this applies only to the specific Loc/Rot/Scale
coordinate that are defined in the Ipo channels as the channels
are now independent.

3. When the objects are converted from Blender to the BGE, the
delta Loc/Rot/Scale that might result from initial non-zero values
in delta Ipo Curves will be ignored. However, as soon as the
delta Ipo curve is activated, the non-zero values will be taken
into account and the object will jump to the same Loc/Rot/Scale
situation as in Blender. Note that delta Ipo curves with initial
non-zero values is bad practice; logically, a delta Ipo curver
should always start from 0.

4. If you define both a global and delta channel of the same
type (LocX and DLocX), the result will be a global channel equivalent
to the sum of the two channels (LocX+DLocX).

Add CMP_premulkey.c to Win32 project

Baking now does material texture anti-aliasing if the OSA button is
enabled, result of that is mainly visible for image textures.

Added two UV features (Apricot request):

- Alt+click edge loop select.
- Next to Align X/Y, Align Auto which will pick X or Y automatically,
should give the expected result for nearly all cases.

Bugfix: recent insert keyframe optimization had an error in it
that made replacing the last keyframe not work correct.

Action editor keys copy/paste did not create ipo curves if they didn't
exist yet, now it creates them if they are in the copy buffer.

Insert Keyframe Optimisations:

Now a binary search is performed instead of a linear one to see where to insert a keyframe. It also checks first whether the keyframe is out of the bounds of the existing ones (as most of the time, keyframes are inserted at the end of the array).

When using the .BVH importer to import a particularly large file, the time taken to add the keyframes improved by about 1 second. Other factors probably limited the improvement seen.

Moved recent addition of get/setPixelF to get/setPixelHDR and kept get/setPixelF limited to 0.0-1.0 range, to prevent existing scripts breaking.

Bugfix for wrong initial cloth settings pretending to be cotton

quick fix for null check that crashed blender when reading some files.

image render to billboard was rotating UV's incorrectly, also make use of texface alpha rather then making many materials with textures.

Added python access to TEXFACE_ALPHA

Cloth bugfix for 1. reset of cloth sim during render with vector blur when cache was not protected, 2. fix of bad vector blur for cloth, put fluidsim like function in to get real speed vectors

Added an Alpha Convert compositor node, to convert between
premultiplied and key alpha.

Bugfix: render instancing didn't work correct with layer ipo's,
each instance should have it's own layer.

Bugfixes:

* Menus could no longer have their items accessed by number (i.e. W-5 didn't run merge tool in EditMode when accessed by keyboard). This was caused by my commit for BUTM (there was some extra code there that isn't really needed, but was causing havok).
* NumPad can now be used for the above feature too now
* Typo in error message in Constraints PyAPI

fix for cam.setScale(), cam.setClipStart(), cam.setClipEnd() and
cam.setDrawSize(), they would raise errors when setting ints. but used not to.
better tooltips for Uv Stretch

Tiny tweak, added a space in the node title between custom name and node type.
