News in this version:
- Solve some limitations of walkthrough mode (fdo#81425)
- Multisampling (better rendering quality, mainly at the edges)
- Better error handling (no crash in case of invalid input file)

Also remove the tools/solar.h included from tools/debug.hxx. The include of solar.h
header was necessary in some cases because of a macro or a typedef that was needed.

In general glTF shader files does not contain version
directives and in some case it make shader compiler
using GLSL 1.1 which leads to that the shader compiler
fails.
So we need to append the choosen version number which is
GLSL 1.3 in case of libgltf, but this also means that
from that point OpenGL 3.0 is the new reuirements since
GLSL 1.3 is available only from that version.

since all two of the actual call-sites only care about whether
it is a valid presentation or not, not what kind of presentation it is.

Base line is OpenGL 2.1 + extensions:
GL_ARB_framebuffer_object (part of OpenGL 3.0) for
glGenFramebuffers, glGenRenderbuffers...
GL_ARB_vertex_array_object (part of OpenGL 3.0) for
glGenVertexArrays, glBindVertexArray...
GL_ARB_sampler_objects (part of OpenGL 3.3) for
glGenSamplers, glBindSampler...

Camera moves by click and drag, with checking the last mouse
position we can make sure click was done inside the window
before drag.
Resizing can trigger drag event, but not click event.

If any error occurs related to glTF rendering, a question
mark is displayed at the place of the OpenGL window
(Question mark is a general concept of media objects).

Reproduce:
- Insert two models
- Play first model
- Delete second model
Result: crash (windows) or first model disappear from the
opengl window (linux).

Building:
- The new tarball has reasonable build system so
build libgltf as external package instead of compiling
source files directly.
- Freetype dependancy is removed
Improvements comes with the new libgltf
- Can rotate the models too (orbit mode)
- Two camera handling mode: walkthrough and orbit
(press M to change).
- gltf_animation_set_time() works
- FPS can be displayed without freetype (press F)
Additional notes:
- There were some bugs/regressions which are fixed
during the integration (see patches).
- License files are uddated now.
- libgltf building is enabled only on those platforms
on which gltf support actually works (windows and linux)

libgltf: Parser releases the glTFHandle, but it was not connected to
the corresponding handle by RenderScene::initScene. So when rendering
stopped during file loading because of missing file, Parser's handle
member was an uninitialized pointer so it crashed by calling release
method.

Plus fix some problems related to temp files.
e.g. kmz converter was creating temp files next
to the input file.

There is no an accepted mime type for glTF models yet, so
follow collada's mime type: model/vnd.collada+xml.
