4842b1ca13 rework stream operators for libmath
libmath itself doesn't expose any stream operators anymore. However,
libutils is able to automatically print libmath types into its
io::ostream -- however matrices are not formatted nicely.

Added a new optional library, libmathio, that provides std::ostream
operators for all libmath types. libmathio does a better job at
formating matrices.

Also removed apply() and map() from libmath because there were not used
anywhere and they forced us to depend on <functional> in public headers.

67406c42ec Clamp viewport width to prevent floating point exception.
To trigger an exception users could either shrink the window or enlarge
the sidebar. Constraining both of these is somewhat tricky so let's
just clamp the viewport width at a low level.

3105a8330e remove unneeded includes in public headers
Replace with forward declarations if needed and includes in .cpp that
now need them.
The idea here is to have our headers have the least amount of impact as
possible on our clients (e.g. compilation time).

2854c0627d camutils: add support for Builder pattern.
This makes the upcoming Java bindings simpler and improves parity with
existing API conventions.

Note that camutils does not depend on filament and therefore cannot use
BuilderBase.

Note that the Manipulator Builder state is public which breaks with
convention but makes implementation simple and allows C++ clients to
continue using modern initializer syntax if they wish.

7d548151d7 Introduce camutils library.
This moves the camera manipulator into its own library and adds new
functionality including a new "Google Maps" manipulator and a bookmark
feature to facilitate camera animation.

Java bindings and an Android sample will land later this week.

dd8c0a759f Improve IBL's diffuse
If spherical harmonics are not specified in IndirectLight (i.e. 
omitted entirely), we instead use the roughness==1 LOD in the shader.
This produce much better results with absolute HDR environment, and 
generally works better more often.

This is now the preferred solution.

For cases where spherical harmonicas are better or preferred, they
can simply be supplied as before.

0e967726de Simplify CameraManipulator.
This removes a lot of code and will make it easier to migrate into a new
library with Java bindings, etc.

- The clipping planes and projection matrix were unused, removed them.

- In split view mode, our demos were using only 2 of the 3 manipulators,
  removed one.

- Instead of callbacks and update methods, users can simply ask for the
  current matrix at every frame.

- The manipulator's job is to consume mouse events and maintain an
  "look at" basis, there is no need to store a reference to a Filament
  Camera.

dad814e046 Fix a long standing bug preventing the use of transparent views (#1893)
Fix #1165

In order to use transparent views, post-processing had to be disabled
because we were not able to blit post-processed buffers with blending.
This is now fixed by simply reverting to a quad.

A side effect of this, is improved performance when a scaling blit is
needed when MSAA is active.


This also introduced new "bugs", or at least weird behaviors: the
system needs to know when blending is needed, and this has to be
based on heuristics (unless we add a new api). Currently the heuristic
is that the COLOR buffer is not discarded and the view is cleared with 
an alpha value (or not cleared).

34ef2a871f Stop using compressed IBL's in more places.
We use R11F_G11F_B10F for HDR so we should stop checking for compressed
IBL files.

Also, make the glTF sample on web more consistent with the default
settings used by gltf_viewer on native and use venetian_crossroads
instead of syferfontein.

56c2d6338e Add spherical harmonics parser, reduce code duplication.
This uses strtof rather than stringstream and provides a common location
that can be leveraged by the upcoming JNI bindings.

Note that this new method lives in KtxBundle rather than KtxUtility. The
latter creates Filament textures and therefore does not get built into
libimage.

2ded1c955f cmgen and filament now support RGB_10_11_11_REV
- RGB_11_11_10 is exported in a RGBA PNG file where the 4 channels are
  used as a uint32 storing a RGB_10_11_11_REV pixel.
  We use the .rgb32f extension, and those PNG files contain garbage 
  when seen in a PNG viewer.

- This is now the default for the -x option.

- compressed KTX files don't encode RGBM, which means they can't
  support HDR, unless an HDR compression scheme is used.

2b5f6cafa6 Separate src/driver into its own library
In this first step, we just "blindly" move everything under src/driver
to a new library libbackend.a. And all headers are moved under
private/backend.

Note that "driver" is renamed "backend", but namespaces are unchanged for now.

Later we'll have to untangle the actual private headers from public
ones and ideally not have any private headers.

7bc6b3c818 Replace gltf_viewer and introduce gltfio::SimpleViewer.
The new gltf_viewer app has an optional zero-arguments mode whereby it
loads a resgen-embedded binary model, which is useful for quick
sanity testing. If you don't specify an IBL, it loads a compressed
version of the pillars IBL.

84eb9547f5 Tangent-related fixups in MeshAssimp.
Assimp's CalcTangentSpace deviates from de facto glTF 2.0 so we were
compensating for this with an unconditional fixup in MeshAssimp. However
the fixup should apply only when CalcTangentSpace is active, i.e. when
the model is missing tangents.

This makes it so that NormalTangentMirrorTest (has tangents) and
NormalTangentTest (needs tangents) both look reasonable.

I also noticed that MeshAssimp was inexplicably applying
aiProcess_CalcTangentSpace twice: once as a flag, and once as a
post-process. I removed the latter.

This will be fixed in the upcoming cgltf-based loader, which will
use our officially-sanctioned utility method in VertexBuffer.

See #528
