Detailed Description

General (simple) 2D texture class

    NOTE: Currently reads only simple, uncompressed Microsoft Bitmap (BMP) files.
    NOTE: The width & height of the bitmap is truncated to powers of 2.

    Slots:
   	1. width		(LcNumber)		Size of the texture map.
   	2. height		(LcNumber)		Size of the texture map.
   	3. redScale		(LcNumber)		for glPixelTransferf(GL_RED_SCALE)
   	4. redBias		(LcNumber)		for glPixelTransferf(GL_RED_BIAS)
   	5. greenScale	(LcNumber)		for glPixelTransferf(GL_GREEN_SCALE)
   	6. greenBias	(LcNumber)		for glPixelTransferf(GL_GREEN_BIAS)
   	7. blueScale	(LcNumber)		for glPixelTransferf(GL_BLUE_SCALE)
   	8. blueBias		(LcNumber)		for glPixelTransferf(GL_BLUE_BIAS)
   	9. wrapS		(LcIdent)		for glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S)
      10. wrapT		(LcIdent)		for glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T)
      11. magFilter	(LcIdent)		for glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER)
      12. minFilter	(LcIdent)		for glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER)
      13. path		(LcString)		Path to the texture directory.
      14. file		(LcString)		Texture file name.
