e83673ffb8 Increase epsilon for RGB2HCV to fix mobile NaN 
Some mobile GPUs end up dividing by "zero" with the previous epsilon
value. The larger epsilon doesn't cause any problems on systems which
didn't exhibit the bug (like my main dev machine).

8a1f3306b7 Check if x has been incremented to OR above the width. 
Fixes a bug with the convex hull calculation where the bounds could not
be calculated for certain costumes with non-integer sizes.

59f6492742 Use isTouching methods in RenderWebGL.pick and getConvexHull 
Use Drawable.isTouching and Skin.isTouching to implement pick and
_getConvexHullPointsForDrawable to emulate rendering the drawable's
silhouette and determining what is picked or the points for a convex
hull.

448c88e637 Add EffectTransform 
EffectTransform transforms a point based on a Drawable's effect uniform
values mimicking the texcoord0 transformation in the shader. This way a
point in the Drawable space can know if its touching its silhouette
when the Drawable has effects active.

1926b49ebc Add Silhouette class 
Silhouette emulates silhouette rendering. Performing tests like
RenderWebGL.pick can use Silhouette in place of reading a silhouette
rendering from the GPU.

Silhouette.isTouching(vec) takes a texture coordinate vector and checks
if the corresponding location is opaque or not for the underlying
information.

3380aa938f Fix for Touching color white always returns "true" #710 
So the issue is simple... We start by filling the detector canvas with
the color white, then layer over this the costumes we are want to detect
white colors in (but clip to the shape of the costumre we are detecting
against) then the areas that were clipped will still be white (the
background fill color). So we detect white no matter what.

b060c07db1 Compare new setRotationCenter values after truncating to 32bit 
`Skin._rotationCenter` is a twgl vector or said another way a
Float32Array. JavaScript casts values stored in this array as 32 bit
floats instead of JavaScript's standard 64 bit floats. Comparing the
equality, like `setRotationCenter` does, of a 64 bit float against a
value stored in a 32 bit container will virtually always be false.
Truncating the new value into a 32 bit (losing precision) will give a
more useful comparison and remove a lot of current false positives.
