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).
