Implement the webgpu.h swapchains on Metal
The webgpu.h surface-based swapchains are implement on Metal which required adding the present mode to NewSwapChainBase. Additional automated tests are added which require getting the Instance so a new getter is added to DawnTest. Additional some the state tracking of swapchains is performed in the backend, so the SwapChainValidationTests are turned into regular DawnTests so they can check backends do the correct state tracking. To not lose coverage of the Null backend, a NullBackend() DawnTestParam factory is added. Finally swapchains cannot be entirely tested in an automated fashion, so a new example is added called "ManualSwapChainTests" that allows manually checking a number of properties. Documentation of the controls and a manual test plan is in a comment at the top of the example's source.

|

// This is an example to manually test swapchain code. Controls are the following, scoped to the
|
||||
// currently focused window:
|
||||
// - W: creates a new window.
|
||||
// - L: Latches the current swapchain, to check what happens when the window changes but not the
|
||||
// swapchain.
|
||||
// - R: switches the rendering mode, between "The Red Triangle" and color-cycling clears that's
|
||||
// (WARNING) likely seizure inducing.
|
||||
// - D: cycles the divisor for the swapchain size.
|
||||
// - P: switches present modes.
|
||||
//
|
||||
// Closing all the windows exits the example. ^C also works.
|
||||
//
|
||||
// Things to test manually:
|
||||
//
|
||||
// - Basic tests (with the triangle render mode):
|
||||
// - Check the triangle is red on a black background and with the pointy side up.
|
||||
// - Cycle render modes a bunch and check that the triangle background is always solid black.
|
||||
// - Check that rendering triangles to multiple windows works.
|
||||
//
|
||||
// - Present mode single-window tests (with cycling color render mode):
|
||||
// - Check that Fifo cycles at about 1 cycle per second and has no tearing.
|
||||
// - Check that Mailbox cycles faster than Fifo and has no tearing.
|
||||
// - Check that Immediate cycles faster than Fifo, it is allowed to have tearing. (dragging
|
||||
// between two monitors can help see tearing)
|
||||
//
|
||||
// - Present mode multi-window tests, it should have the same results as single-window tests when
|
||||
// all windows are in the same present mode. In mixed present modes only Immediate windows are
|
||||
// allowed to tear.
|
||||
//
|
||||
// - Resizing tests (with the triangle render mode):
|
||||
// - Check that cycling divisors on the triangle produces lower and lower resolution triangles.
|
||||
// - Check latching the swapchain config and resizing the window a bunch (smaller, bigger, and
|
||||
// diagonal aspect ratio).
|
||||
//
|
||||
// - Config change tests:
|
||||
// - Check that cycling between present modes works.
|
||||
// - TODO can't be tested yet: check cycling the same window over multiple devices.
|
||||
// - TODO can't be tested yet: check cycling the same window over multiple formats.
