Latest Emscripten seems to emit correct values.

- Backend: WebGPU: Fix building for latest WebGPU specs (remove implicit layout generation).

(#6117, #4116, #3632) [@tonygrue, @bfierz]
|

- Examples: refactord all examples to use a "MainLoopStep()" function. This is in order
|
||||
to be able to trivially make some compile with Emscripten. (#2492, #3699)
|
||||
While not all examples are expected to compile on Emscripten, we try to keep all of them
|
||||
as close as possible to each others.
|
||||
- Examples: Win32: Fixed examples using RegisterClassW() since 1.89 to also call
|
||||
DefWindowProcW() instead of DefWindowProc() so that title text are correctly converted
|
||||
when application is compiled without /DUNICODE. (#5725, #5961, #5975) [@markreidvfx]
