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
