TGA's can claim to use less palette colors than they later do.
We only support 8-bit palettes, so to make this safer lets just always allocate at least 256 bytes.

We had 4 near identical functions, those now all call buildProjectionMatrixPerspectiveFov
They were a bit hard to check for errors otherwise.
Especially with the tiny confusing non-differences like one using (a-b) and other -(b-a)
Also new one uses matrix template parameter in case someone needs for example a high-precision matrix.

Removing includes which were not needed by headers
Note that if you include those headers directly (instead of including irrlicht.h) you may have to add some new includes now.
Thought I generally tried to avoid removing headers where it leads to too much changes in user-code
Reason was mainly that IntelliSense in VisualStudio 17.7 added a new feature which shows those unused headers :)
Has to be used a bit careful as it doesn't know about defines and other platforms
And I only did clean up public headers so far (will probably do some more later or another time)

Note: Due to OSX always failing merge OSX it's rather applying a second patch
from Ryan Schmidt from bugreport #462 to trunk
(Not sure why svn merging always fails for OSX. Probably related to MacOSX files getting moved in the past. Was that done without svn move commands? I guess that can't be fixed anymore now)

Note that 6514 couldn't be merged as the xcode project seems to have been rewritten and the irrFramework-Info.plist no longer exists in trunk.

Note those were mostly backport, so trunk already had most changes.
Also we've not merged all from 1.8 branch, will need another merge (backports tend to cause lots of ugly conflicts, so have to split this a bit)

Also document that gl_FrontMaterial is no longer supported in Irrlicht 1.9 (this has been the case for a few years, I just never noticed this was changed as I never even knew that was possible in the past...). Will keep it that way is it's definitely going in the right direction (getting rid of legacy support and going towards OpenGL core instead),

What Irrlicht calls ShaderConstants is called uniforms by everyone else. So let's mention this at least.
Also reworked setVertexShaderConstant interface had an example for the old interface in the header.

Fix: When appending to an empty mesh boundingbox has to be initialized with first position
Adding updateBoundingBox parameter as there is a bit costs involved in updating that and it might not be necessary at that point
Default is still to do it - and with the default parameter it's at least compile compatible to old interface (unless users created their own meshbuffers).
Optimizing the copying of vertices in CDynamicMeshBuffer::append by using memset when possible instead of pushing each vertex (which goes through quite a few virtual functions)

Couldn't allocate enough memory before appending several buffers for all of them as first append shrunk the memory again.

Doesn't change it's own type - so can still drop data. Or overflow 16-bit buffers (which creates broken models, but no crashes).
But it no longer has a problem adding 16-bit index-buffers to a 32-bit index-buffer for example.

Some in CMeshBuffer got disabled in svn r1515 (before Irrlicht 1.7) without comment.
I suspect reason might have been that they are a bit unsafe and it was meant to be reworked.
Maybe was planned to put that into MeshManipulator?
And CDynamicMeshBuffer never had them.
Anyway, it's useful stuff and having functions do nothing doesn't help. So now they do at least basic work.
Meaning - as long as index and vertex types are identical it's possible to attach meshbuffers again.
While totally ignoring things like 16-bit index overflow for now (so could be improved).
It would probably be better if attach functions had info about vertex/index types, but just keeping interface as it is/was for now.
This also fixes Bug #310 reported by Gaz.

SMaterialLayers are now identical when both have identity matrices.
Before it didn't consider them identical when one layer had set the identity matrix explicitly and the other didn't.
Generally didn't matter, just caused very rarely some extra state switches in the drivers. And just as rarely had a cheaper comparison. Just seems more correct this way.
operator= no longer releases texture memory which was allocated at one point.
Unless explicitly requested such memory is now always released later in the destructor.
This can avoid quite a few memory allocations/released in the driver. Usually not a noticeable performance difference on most platforms. But it can help avoid memory fragmentation.
We instead use an extra bool now to tell if the texture memory is used. So slight increase in SMaterialLayer and SMaterial size. But I did a quick performance test and this had no negative influence here, while it did improve speed in the case where it switched between material layers using/not using texture matrices a bit.

Wasn't ever used by anything and not that well defined anyway.
So they all just passed it on to the drivers. And then sometimes the driver version was called and sometimes the IMaterialRendererServices version. So now everything just calls the driver - all places which need it have access to the driver anyway. Also made the driver version non-virtual for now. If someone actually really needs this for some reason I can add it back as virtual function directly in IVideoDriver. But I doubt it - the interface was hardly accessible until recently and originally only meant for internal stuff.
GLES version still to do, but checked them earlier and they also just do nothing with it.

So far SceneManager always sorted Nodes per render stage.
Now we allow sorting per mesh-buffer per render stage by creating a new node for each mesh-buffer.
It's only supported for CMeshSceneNode so far.
This allows to enable better transparency sorting for meshes which have transparent buffers.
Previously those always got rendered in the order in which they got added and ignored mesh-buffer bounding-boxes, but just used the bbox of the full mesh. Now they can use the bbox for each meshbuffer which can sometimes avoid render errors.
Also depending on the scene this can be quite a bit faster because it can help reduce texture changes. We sort solid nodes per texture, but only per node. So nodes with several textures had a texture switch between rendering each meshbuffer. And those are rather expensive in Irrlicht right now (and we support no bindless textures yet...)
Lastly it's now also used to buffer the render-stage. Checking this twice (once in registering the node and once in render) constantly showed up in the profiler. Which was a bit surprising really, but anyway - now it's gone.
I tried to keep it working for all cases we had before (all kind of situations, like when people may want to call render() outside the SceneManager). But not (yet) supporting the case of changing the meshbuffers (adding or removing some) without calling setMesh() again. Reason is that this wasn't well supported before either (node materials never updated). So for now I just assume people will call setMesh() again when they change the mesh.

New AbsPosUpdateBehavior which makes updateAbsolutePosition calls behave as if a node had no parent.
Allows for micro optimizations in cases where we have non-moving root node (all scenenodes are always added to the SceneManager which is generally not moved but it's transformation is still multiplied each frame for each node)
As a side-effect this also allows abusing the SceneManager to group objects without affecting transformations.
No real extra cost since I added ESNUA_TRANSFORM_POSITION already.
Thought turns out those matrix transformations are so fast that I also didn't noticed any difference in tests with > 20.000 nodes.

Shouldn't have been removed with last commit.
But adding some comments as it's slightly confusing.

This makes it possible to set high-level shader constants (which are attached to shader programs) to be set outside
of OnSetConstants.
IShaderConstantSetCallBack::OnCreate has it set automatically now so it works the same as OnSetConstants.
D3D9 and burnings both work different, so there hadn't been a problem with those.
git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6469 dfc29bdd-3216-0410-991c-e03cc46cb475
Accessing IMaterialRendererServices outside of OnSetConstants can be useful and Irrlicht made this a bit too hard to access.
Also OnCreate allows actually for nicer code where initialization and update of shader constants are strictly separated (see changed example).
git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6465 dfc29bdd-3216-0410-991c-e03cc46cb475
Basically now the same as GLSL material renderer already worked.
Before it was using IMaterialRendererServices from CD3D9Driver, but there had been several problems with that:
- The d3d9 driver called functions through the CD3D9MaterialRenderer interface, but CD3D9HLSLMaterialRenderer is not (or maybe no longer?) derived from that class. Reason it still worked was accidental luck - the same functions had been in the same order and due to casts the compiler wasn't noticing it was calling the functions of an unrelated class.
- It was making calls to set shader constants depend on the currently set material in the driver. Which was not necessary and just prevents we can use the IMaterialRendererServices interface without setting the material first (how I found the bug).
Still some problems left for now:
- There's 2 ways to call shader constants. One seems to be only used by hi-level shaders which links constants to the shader. The the other only by low-level shaders which uses global (shader independent) registers.
So maybe this should be 2 interfaces? But not certain, glsl material renderer seems to prevent setting the global registers, but maybe those could be used additionally? I've still allowed it for now in HLSL, just in case it had it's uses.
- setBasicRenderStates probably should not be in IMaterialRendererServices. I'm not seeing any case where this isn't just passed on to the driver. And all classes using it have access to the driver unless I missed one. So probably can just avoid that additional indirection and kick that out of the IMaterialRendererServices interface.

This also fixes the combobox which users the listbox like that.
This got broken in [r6454] which had fixed the events send out by the listbox
Note: Still a bit strange behaviour when leaving the combobox at the bottom, but that was already that way in Irrlicht 1.8, so I've got to investigate that on it's own.
