Fixes #2 Minimum scale never properly set when calling com.lyft.android.scissors.TouchManager.resetFor(...) Details:
- setMinimumScale(...) in resetFor() prematurely called before this.bitmapWidth/Height were set.
- computeLimit(...) in resetFor() called without proper scaling.
- setMinimumScale(...) method was erroneously always set to 1.0f, when bitmap was smaller than viewport.
Add Add proguard rules for optional dependencies.
Initial release.
