Browse Source 
* Revert "feat: Skia for Android (#1731)"

This reverts commit a7c137da07.

* Remove some skia

* Remove all the Skia stuff.

* Update useFrameProcessor.ts

* Update lockfiles

* fix: Use native Preview again

* Use `OpenGLTexture&` again

* Remove `PreviewOutput` (we use `SurfaceView` in parallel)

* fix: Log photo widths

* fix: Fix cpplint

A Camera Frame Renderer powered by Skia.
It provides two Contexts, one offscreen and one onscreen.
- Offscreen Context: Allows you to render a Frame into a Skia Canvas and draw onto it using Skia commands
- Onscreen Context: Allows you to render a Frame from the offscreen context onto a Layer allowing it to be displayed for Preview.
The two contexts may run at different Frame Rates.
*/

Renders the given Camera Frame to the offscreen Skia Canvas.
The given callback will be executed with a reference to the Skia Canvas
for the user to perform draw operations on (in this case, through a JS Frame Processor)
*/
- (void)renderCameraFrameToOffscreenSurface:(CMSampleBufferRef _Nonnull)sampleBuffer withDrawCallback:(draw_callback_t _Nonnull)callback;

Renders the latest Frame to the onscreen Layer.
This should be called everytime you want the UI to update, e.g. for 60 FPS; every 16.66ms.
