## @struct PIX
# The basic element of a TCAS FX, it contains dozens of DIPs (dynamic isolated pixels).
# It is a tuple that has the following structure ((initX, initY), (width, height), (r1, g1, b1, a1, r2, g2, b2, a2, r3, ...)).
#
# initX a float, offset of the PIX in the horizontal direction
#
# initY a float, offset of the PIX in the vertical direction
#
# width an integer, width of the PIX
#
# height an integer, height of the PIX
#
# rgba all integers, rgba colors of the PIX
#
# Remarks: Although DIP is the basic unit of TCAS files, it is not easy to handle when come to make TCAS FX.
# So in TCAS FX, PIX is the one which is regarded as the basic unit and most tcaxLib APIs are used to manipulate PIXs.
# However DIP can still be used when needed. Most tcaxLib APIs receive PIX as an input parameter and return a new PIX as the output result.
# Note that, you should be definitely sure if you are going to construct your own PIX object through simple assignment operation other than
# APIs provided by tcaxLib, for instance, PIX = ((initX, initY), (width, height), (r1, g1, b1, a1, r2, g2, b2, a2, r3, ...)), any mistake may
# lead to the crash of the host program.
