Tracking issue for vertical rendering to spec

[tmickel]

Match design from #3. This includes:

• Add one of each of those block types to blocks_vertical so we know what we're up against.
• Fix actual sizing of blocks (they are larger in spec - to be zoomed down for desktop)
• Fix corner radii on most blocks
• Adding a notch to the bottom of statement inputs (bays/holes for blocks)
• Make notch using Bezier curves (see Notch Curves on the pixel grid #93 for reference - these should be turned on their side for vertical)
• Fix font sizes to match spec
• Don't draw holes for shadow blocks in the parent block
• Draw field chrome for shadow blocks:
  • field_number-type chrome (lots of corner radius)
  • field_text-type chrome (less corner radius)
  • drop-down-type chrome
  • boolean-type chrome
• Rendering of reporter-type blocks. Blocks with no next, no previous connections, and an output should render as reporters. The shape of the block depends on output type (either boolean-type with angle corners or value-type with rounded corners).
• Center alignment of text (might get this for free if Horizontal baseline alignment across text, fields, inline values, and external values. google/blockly#333 is implemented in upstream)
• Fixing the hat block shape to spec
• Alignment of fields horizontally (LEFT/RIGHT/CENTER)
• Minimum positioning of second field (see: if, "say" examples), only if there is a previous connection.
• C-blocks have different minimum width
• Need to make size of C-block bottoms always match top. I.e., the width of all rows should match the maximum width of a single row...

Closing and making a couple of new issues.
