when the browser viewport is smaller than half the island, the island's position is wrong and it will be cut off at the top, and leaves too much water at the bottom

Probably going to use the depth buffer for this.

Render units/buildings into a separate frame buffer so we can tell what the user clicked on.

Sprite sheets are created with TexturePacker. It can be configured to remove whitespace on all 4 sides of the image (trimming). This can save a lot of space in the textures, but complicates rendering.

I'm thinking about rendering a quad the size of the original, but passing offset information to the fragment shader that allows it to ignores texel that fall into the trimmed regions.

Not necessary at this point as I haven't hit any bottlenecks yet, but I'd like to try anyway.

To render a status icon for example, we only need to pass position information and a sprite index, transformation and texturing happens inside the shaders.

It's not needed right now, but 'webkitRequestAnimationFrame' is hardcoded and raises errors in other browsers.

right now, all images use the same rotation (45°). this is not a big issue for NxN tiles buildings, however MxN needs special handling (salt pond, brickyard ..)
