Implement Bitmap.copy, text layouting (#1455)

* Bitmap: Use provided config

* Bitmap: implement copy

* Bitmap: Simplify getPixels

This also fixes a bug where the returned data may not be in the correct
format

Android getPixels():
> The returned colors are non-premultiplied ARGB values in the sRGB color space.
BufferedImage getRGB():
> Returns an array of integer pixels in the default RGB color model (TYPE_INT_ARGB) and default sRGB color space

* Stub TextPaint and Paint

* Paint: Implement some required functions

* Stub StaticLayout and Layout

* Implement some Paint support

* Draw Bounds

* WebP write support

* First text rendering

* Paint: Fix text size, font metrics

* Paint: Fix not copying new properties

Fixes font size in draw

* Canvas: Stroke add cap/join for better aliasing

Otherwise we get bad artifacts on sharp corners

Based on https://stackoverflow.com/a/35222059/

* Remove logs

* Canvas: Implement other drawText methods

* Bitmap: support erase

* Layout: Fix text direction

Should be LTR, otherwise 0 is read, which is automatically interpreted
as RTL without explicit check

* Bitmap: scale to destination rectangle

* Canvas: drawBitmap with just x/y

* Bitmap: Convert image on JPEG export to RGB

JPEG does not support alpha, so will throw "bogus color space"

* Switch to newer fork
