\/** @def CC_FIX_ARTIFACTS_BY_STRECHING_TEXEL
\nIf enabled, the texture coordinates will be calculated by using this formula:
\n– texCoord.left = (rect.origin.x*2+1) \/ (texture.wide*2);
\n– texCoord.right = texCoord.left + (rect.size.width*2-2)\/(texture.wide*2);<\/p>\n

The same for bottom and top.<\/p>\n

This formula prevents artifacts by using 99% of the texture.
\nThe “correct” way to prevent artifacts is by using the spritesheet-artifact-fixer.py or a similar tool.<\/p>\n

Affected nodes:
\n– CCSprite \/ CCSpriteBatchNode and subclasses: CCLabelBMFont, CCTMXTiledMap
\n– CCLabelAtlas
\n– CCQuadParticleSystem
\n– CCTileMap<\/p>\n

To enabled set it to 1. Disabled by default.<\/p>\n

@since v0.99.5
