ImageBuff([width,height[,color[,scale]]])
width, height: size of buffer in pixel.
default: buffer not allocated.
color: initial value of RGB channels. Alpha channel is 255.
Possible values: 0(black=default) -> 255 (white)
scale: True or False to enable or disable fast scaling
default: False
This constructors eliminates the need to use the load function
when you just want to initialize the image buffer to black or white.
