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

The same for bottom and top.

This formula prevents artifacts by using 99% of the texture.
The "correct" way to prevent artifacts is by using the spritesheet-artifact-fixer.py or a similar tool.

Affected nodes:
- CCSprite / CCSpriteBatchNode and subclasses: CCBitmapFontAtlas, CCTMXTiledMap
- CCLabelAtlas
- CCQuadParticleSystem
- CCTileMap

To enabled set it to 1. Disabled by default.
