from getting selected. Use e.preventDefault instead of adding and removing
classes on mousedown and mouseup. This keeps the browser from having to
potentially recacluate style on mousedown and mouseup events.
These were intended for the htmlInput, not the SVG blocklyText. Adding these in was causing the blocklyText element to get selected sometimes in webkit browsers.

css to mark text as unselectable instead. I can't prove this is
significantly faster with numbers since the call to setup the time out
costs ~.1ms and the call when the timer fires is ~.05. This happens on almost
every mouse event though. Plus, it seems to remove a flicker of highlighting when
frames are skipped and keeps scrolling via the scrollbar from highlighting.
-Convert most constants in the code to use multiplications of GRID_UNIT (4px). This lets us be consistent with Carl's specs and helps explain the numbers a little better.
-Implement notches using cubic curves instead of arcs. This version matches the spec pretty much exactly. As part of this, remove NOTCH_BASE_HEIGHT which is no longer relevant.
-Slight simplification of renderCompute_ (which calculates metrics).
-Fixed SEP_SPACE_X and SEP_SPACE_Y to be the correct number of grid units. Our blocks before were slightly too small, now they are the right size.
-Implement the correct corner radius, hat/end hat radius.
-Add fixed ICON_WIDTH and ICON_HEIGHT, i.e., always size the icons to 40x40px as according to the spec.
-Add fixed STATEMENT_BLOCK_SPACE to represent the size of the bar above forever/repeat/pants blocks. Previously the code was assuming this was SEP_SPACE_Y, when in fact the spec has it as larger (4 units).
-Add accurate MIN_BLOCK_X and MIN_BLOCK_Y for simpler calculation of minimum bay size.
-Remove some unused SVG paths (INNER_TOP_LEFT_CORNER, INNER_BOTTOM_LEFT_CORNER).
-Remove extra code in getHeightWidth which caused a bug in rendering forever-in-repeat.
-Fix stroke width around the blocks to be 1px, according to spec.
I've checked that everything lines up with Carl's spec images at 8x zoom.
This should implement #69, #70, #71, #72, #74, and #75 (not 73 as we haven't done that input yet).
