Grid vs Grid collision ported from FlashPunk
Fixing Spritemap initialization bug on Linux64 target. Bug was caused by dividing _rect.x by _width before _width had been set, resulting in a rect with x=NaN. Checking that width is nonzero fixes the issue.
Allow to have spacing on tileset on Atlas plateform
Allow tileset spacing on other target
Check that Spritemap dimensions are multiples of frame dimensions
Added support for middle and right mouse button
