Adds a flag to create non-resizeable windows.
Since the number of parameters is getting awkward, extracts
window-related parameters and engine-related parameters into structs for
clarity. This also removes some duplication in method signatures.
The window parameters struct change is also made to the C++ wrapper,
making this a breaking change for the runners.
Fixes https://github.com/flutter/flutter/issues/37623
Rather than running the runloop forever, have the API expose an incremental runloop. This allows clients to do other processing if they need it.
This allows for removing the odd construction of having knowledge of GTK event handling built into the library even though nothing in the library uses it; instead runner applications that use GTK plugins (such as FDE's testbed) can do that processing at the application level instead.
Adds methods to get and set the window size, as well as to query the
window's scale factor. This is useful both for custom clients, and for
building a window resize plugin to prototype what will eventually likely
be a system channel.
Plugins may need to be able to access functions affecting the GLFW
window (e.g., a plugin to resize the window). This restructures the API
to create a distinction at both the C and C++ level between the window
controller, which provides access to high-level behaviors driving the
Flutter application, and the window, which provides access to functions
to affect the UI state of the window (i.e., wrapped GLFWwindow
functions).
Also provides a PluginRegistrar extension for plugins that need access
to GLFW-specific functionality.
Changes include:
- File structure
- Header guards
- Include paths
- Namespaces
- Integration with the engine's GN build
- Conversion from jsoncpp to rapidjson
- Style and clang-format adjustment to match engine repository
