[WPE] Add a tutorial about writing a WPE platform implementation
https://bugs.webkit.org/show_bug.cgi?id=322277
Reviewed by Carlos Garcia Campos.
This walks through writing a WPE platform implementation concept by
concept — the WPEDisplay/WPEView/WPEToplevel subclasses, rendering,
input, and module registration — using the public API and the built-in
implementations as examples.

[GTK3] Skia compositor: contents are y-flipped when using SHM or GBM mapped
buffers
https://bugs.webkit.org/show_bug.cgi?id=323313
Reviewed by Adrian Perez de Castro.
This is because SkSurface::readPixels already takes into account the
surface origin to return the pixels y-flipped and then in the UI process
we end up flipping again. It's easier and more efficient to never y-flip
for SHM buffer and then only flip in the UI process for GBM mapped
buffers.
