b304ea8fdf Make touching-color test more robust against GPU imprecision 
Previously, the `color-touching-tests.sb2` test "touches a color that
doesn't actually exist right now" would use a sprite with ghost 50,
blended against another sprite, to create the color that "doesn't
actually exist" when the query sprite is skipped. Unfortunately the
blend result was near a bit-boundary and, depending on the specific
hardware used, that test could fail on the GPU. When the renderer uses
the CPU path this test works fine, though, so the existing problem went
unnoticed.

To fix the problem I changed the project to use ghost 30 instead, which
results in a color that is less near a bit boundary and is therefore
less likely to fail on specific hardware.

As an example of what was happening: the `touching color` block was
checking for `RGB(127,101,216)` with a mask of `RGB(0xF8,0xF8,0xF0)`. On
the CPU it would find `RGB(120,99,215)`, which is in range, but on some
GPUs the closest color it could find was `RGB(119,98,215)` which
mismatches on all four of the least significant bits -- one of which is
enabled in the mask.

instead of doing what the comment says. I guess they should match.

update Skin textures with ImageData 
When possible pass ImageData to texture creation and updating to help
remove chance of references that keep canvas and underlying data from
being garbage collected.

replace Silhouette._data with Silhouette._colorData 
_colorData holds the same (and more) data that _data holds. Dropping
the _data array saves a lot of memory for a tiny performance
degradation in regards to touching object.

receive ImageData directly in Silhouette.update 
Given ImageData we can skip drawing the input and getting image data.
This can help if update's color can also use the ImageData directly.

- Adjust the rotation center of the cursor so that its single pixel is

  2-4 stage pixels.
- Add canvas CSS to make most browsers scale the canvases without
  interpolation.
