This change addresses two issues:
[1] It adds a flag field to the blendface call which allows the
caller to indicate whether or not the generated asset is
temporary, and whether or not the asset being replaced should
be explicitly retired fromt the memory cache. The decimal
values correspond to:
0 - Permanent asset, do not expire old asset
1 - Permanent asset, expire old asset
2 - Temporary asset, do not expire old asset
3 - Temporary asset, expire old asset
'3' corresponds to the default behavior seen today, and is
the continued behavior of the non-blendface calls.
[2] The dynamic texture routines are highly-asynchronous and can
be scheduled simultaneously on a multi-core machine. The nature
of the texture management interfaece is such that updates may
be lost, and the nature of asynchornous operation means that
they may be processed out of order. A lock has been added to
ensure that updates are at least atomic. No attempt has been
made to enforce ordering. The lock applies to the SceneObjectPart
being updated and is held for the lifetime of the TextureEntry
used to carry texture updates (the one instance carries all
faces supported by the prim).
Users of these services should remember that the dynamic texture
call is asynchronous and control will be returned *before* the
texture update has actually occurred. As a result, a isubsequent
GetTexture call may not return the expected asset id. A script
must wait for the corresponding TEXTURE_CHANGED event before
retrieving any texture information.

Changes to support client-side image pre-caching in the region. This
commit adds an additional calling sequence to the DynamicTexture data
and URL calls. The new interface allows a dynamic image to be loaded
into a specific object face (rather than the mandatory ALL_SIDES
supported today.
This is in part fulfilment of ticket #458.

The attached patch implements osGetDrawStringSize that looks like:
vector osGetDrawStringSize(string contentType, string text, string
fontName, int fontSize)
in LSL. It is meant to be used in conjunction with the osDraw*
functions. It returns accurate information on the size that a given
string will be rendered given the specified font and font size.
This allows for nicely formatted and positioned text on the generated
image.

OpenSim.Region.Environment into a "framework" part and a modules only
part. This first changeset refactors OpenSim.Region.Environment.Scenes,
OpenSim.Region.Environment.Interfaces, and OpenSim.Region.Interfaces
into OpenSim.Region.Framework.{Interfaces,Scenes} leaving only region
modules in OpenSim.Region.Environment.
The next step will be to move region modules up from
OpenSim.Region.Environment.Modules to OpenSim.Region.CoreModules and
then sort out which modules are really core modules and which should
move out to forge.
I've been very careful to NOT BREAK anything. i hope i've
succeeded. as this is the work of a whole week i hope i managed to
keep track with the applied patches of the last week --- could any of
you that did check in stuff have a look at whether it survived? thx!
