v1.4.0

• Support PNG/JPG images as symbol specifiers, automatically turning them into SVG that includes them (but images must be in the same directory)
• Improve Tilt examples, and add Tetris examples
• Add automatic <image> size detection
• Bug fix: Fix <ellipse> size detection
• Performance: Increase speed when not using some features (CoffeeScript, CSV, XLS, PDF) by pushing require calls as late as possible
• Cleanup tile-width/tile-height documentation and attributes

v1.3.4

• Fix symbol names in output SVG to avoid using colons, which seemed to wreck havoc in SVGs embedded via <img> into HTML.
• Unfortunately, we were encoding all unusual characters using colons, so all SVGs should be regenerated.
• Now code is simpler, just using encodeURIComponent.

v1.3.3

• Add warning about Google Sheet sheet name truncation

v1.3.2

• Fix viewBox computation with overflow (#22)

v1.3.1

• Define space character to qualify as a blank cell for margin detection (for ASCII art in particular)

v1.3.0

• Add row and column feature
• Generated XML now has better indentation because existing spaces get stripped by prettify-xml@1.2.0.

v1.2.4

• Fix zero-size handling, in particular setting <use width/height> to match

v1.2.3

• PDF conversion fixes: fix non-XLS case, show inkscape launch errors

v1.2.2

• Remove excess console.log

v1.2.1

• Render zero-width/zero-height symbols when style="overflow: visible" is specified, despite CSS rules.
