Compile all fiddle examples locally
Motivation: it would be a good idea if the API documentation examples
were checked into the skia repository, so we could make sure they
compile as part of the commit queue.
Fiddle would make/update a named fiddle each time it gets a new
commit of Skia, extracted from the code in the examples/ directory.
The docs would point at those named fiddles. Named fiddles have urls
in the form:
https://fiddle.skia.org/c/@Bitmap_000
Then we would stick a link to the example into the header documentation
like this:
/** Allocates the pixel memory for the bitmap, given its dimensions
and SkColorType. Returns true on success, where success means
either setPixels() or setPixelRef() was called.
@param bitmap SkBitmap containing SkImageInfo as input, and
SkPixelRef as output
@return true if SkPixelRef was allocated
@example https://fiddle.skia.org/c/@Bitmap_000
*/
bool allocPixelRef(SkBitmap* bitmap) override;
There are still around 200 disabled examples that need to be fixed
(these result from API changes since the author left).
