Mathias Agopian 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).

sceneform-1.9pr4

  • Added gltf_bloom Android sample to show gltfio and the RenderTarget API.
  • Added getMaterialInstanceAt to the Java version of RenderableManager.
  • Fix JNI bindings for setting values in parameter arrays.
  • Added JNI bindings for the gltfio library.
  • Fix support for parameter arrays in .mat files.
  • Added support for RGB_11_11_10
  • Removed support for RGBM (warning: source compatibility breakage)
  • IBL cubemap can now be of any size
  • Texture::generatePrefilterMipmap can be used for runtime generation of a reflection cubemap

sceneform-1.9pr3

  • Added Scene.addEntities() to the Java / Kotlin bindings.
  • Improved robustness in the tangents utility for meshes that have tangents and normals.
  • Introduced RenderTarget API that allows View to reference an offscreen render target.
  • Added lucy_bloom sample to demonstrate the new RenderTarget API.
  • Added Screen Space Ambient Occlusion support (SAO)
  • New blending modes: multiply and screen
  • Fixed an issue when sorting blended objects with different blending modes
  • The material property curvatureToRoughness has been replaced with specularAntiAliasing. This new specular anti-aliasing solution offers more control via two new properties: specularAntiAliasingVariance and specularAntiAliasingThreshold. They can also be set on material instances if needed
  • Added specular ambient occlusion to compute a new AO term applied to specular reflections (see specularAmbientOcclusion property in materials)
  • Added multi-bounce ambient occlusion to brighten AO and preserve local color (see multiBounceAmbientOcclusion property in materials)
  • Micro-shadowing is now applied to material ambient occlusion
  • Use a smaller 64x64 DFG LUT on mobile to reduce binary size
  • Added a distance field generator to libimage.
  • JavaScript MaterialInstance now supports vec4 colors.
  • Further reduced filamat binary size by removing reliance on stdlib.
  • Added a new, smaller, version of the filamat library, filamat_lite. Material optimization and compiling for non-OpenGL backends have been removed in favor of a smaller binary size.
  • Implemented hard fences for the Metal backend, enablying dynamic resolution support.
