Methane Kit v0.7.0

iOS and tvOS platforms support was added in this release.

• Tutorials applications:
  • Customised default UI options to make HUD visible by default on iOS.
  • Added iOS screenshots for tutorials.
  • Added keyboards shortcuts for tutorials in README files.
  • Known issue: #101
• Platform libraries:
  • Methane::Platform::AppIOS implementation was added to support iOS and tvOS mobile platforms (closed #12).
  • iOS Alert window implementation was added.
  • Limited input support was added for iOS to translate touches to mouse events (keyboard input is not supported).
  • Moved RenderContext::GetContentScalingFactor and RenderContext::GetFontResolutionDpi methods to Platform::IApp interface with platform dependent implementations. Linux implementation for X11 was added.
• Graphics libraries:
  • Manual memory management was removed from Objective-C Metal graphics implementation due to switching to ARC (automatic reference counting).
  • RenderCommandList::Draw and DrawIndexed calls implementation for Metal was changed to exclude using of start_vertex and start_instance parameters for GPU Family < MTLGPUFamilyApple3 or MTLGPUFamilyMac2, which is essential for working on iOS Simulators.
  • Unsupported Sampler parameters were put under #ifdef APPLE_MACOS to enable tvOS support.
  • Fixed flipping camera projection up-side-down in portrait orientation.
• Tests infrastructure:
  • Add missing test targets to GCov coverage on Ubuntu.
• Build infrastructure:
  • Added CI Build & Test system based on GitHub Actions, which is partially duplicating CI in Azure Pipelines, but enables CI in forked repositories.
    • Fixed shaders code signing by DXC in GitHub agents environment by adding hardcoded path to DXIL.dll in DXC environment.
  • Added Externals/iOS-Toolchain.cmake file from iOS-CMake project to enable iOS & tvOS build configuration.
  • Apple Clang is now used with ARC enabled (automatic reference counting) via -fobjc-arc option.
  • Split MacOS and iOS application .plist configs generation via CMake/MethaneApplication.cmake
  • Split CMake/MethaneGlobalOptions.cmake from CMake/MethaneBuildOptions.cmake to allow including it in the root CMakeLists of external projects to properly set global CMake options.
  • Add support for Apple code signing via APPLE_DEVELOPMENT_TEAM cmake option.
  • Extended Build/Unix/Build.sh script to support iOS / tvOS builds via new command-line arguments --apple-platform, --apple-dev-team and --apple-deploy-target.
  • Added iOS and tvOS configurations to CMakePresets.json.
  • Added iOS and tvOS Simulator builds in Azure Pipelines.
  • Added CLion cmake configurations for iOS.
  • Added iOS and tvOS build instructions to Build/README.md.
  • Fixed iOS app running natively on Mac with Apple Silicon, thanks to @andrejnau for solution of issue #101
