Notes To Self - Steps To VL3

[MicBosi]

• wxWidget 3.x support (https://github.com/MicBosi/VisualizationLibrary/issues/172)
• Rename vl::TextureSampler to vl::TextureImageUnit
• Removed extraneous deprecated TexParameterOverride dead code
• Textures: fix construction (https://github.com/MicBosi/VisualizationLibrary/issues/130)
• Textures: various updates (https://github.com/MicBosi/VisualizationLibrary/issues/189) (maybe later)
• Qt 6 support (https://github.com/MicBosi/VisualizationLibrary/issues/190)
• FramebufferObject + Framebuffer unification + externallyManaged()
• Vector/Matrix updated init (https://github.com/MicBosi/VisualizationLibrary/issues/134)
• size_t for vl::Collection (https://github.com/MicBosi/VisualizationLibrary/issues/138)
• vl::Rendering::renderers () should return a Collection: (https://github.com/MicBosi/VisualizationLibrary/issues/123)
• Merge PRs
• Final testing on Linux Ubuntu 20.04 and VS 2019

• Release 2.1 & docs updates

• Remove GL ES
• Remove fixed function pipeline
  • Fix all broken things:
  • Text rendering support
  • Rework examples depending on fixed function and legacy matrix manipulation
  • Not sure we can still support vlVG
• Use OpenGLFunction object
• Upgrade to GL 4.6
• Final split of OpenGLWidget + OpenGLContext + OpenGLFunctions
  • Fix all broken things and UI bindings
  • Make sure GL resource sharing works
• Add GL 4.6 examples: compute shaders, etc.

• Test and fix on Mac GL 4.1

• VL immediate mode support & examples (booklet)

• [Add depth peeling demo
• Updated volume demo

• Updated fractal demo]

• Bullet physics / PhysX demo test
• glTF support & viewer
• New documentation media
