common options should be consistent among programs

common options should be consistent among programs.

for instance, user defined width and height are sometimes invoked with -w -H and other with -W -H switches

it would be nice to invoke them always with the same syntax :-)

• random_pixels

Usage: ./random_pixels [options]

Options:
  -h            Show this help message
  -w WIDTH      Window width (default: 1280)
  -H HEIGHT     Window height (default: 720)
  -r ROWS       Number of rows (default: 16)
  -c COLS       Number of columns (default: 22)

• text

Usage: ./text [-c cols] [-r rows] [-s speed] [-t text] [-f fontsize] [-T textcolor] [-G gridcolor] [-B bgcolor] [-W width] [-H height] [-d direction]
Colors should be in R,G,B format (e.g., 255,0,0)
Direction: 0=horizontal (default), 1=vertical

@fanfani I've "glued up" the three designs programs we had in a single executable, so most options should be common, and it should be possible to change designs on the fly and do the horizontal flip with the keyboard.

willy@Hitagi pixelwall main$ ./pixelwall -h
The MIAI pixelwall
Usage: ./pixelwall [options]
Options:
  -d <design>      Set design (default: snake)
  -B <color>       Set background color (R,G,B, default: 0,0,0)
  -O <color>       Set border color (R,G,B, default: 130,130,130)
  -r <rows>        Set number of rows (default: 16)
  -c <cols>        Set number of columns (default: 22)
  -w <width>       Set window width (default: 1276)
  -H <height>      Set window height (default: 928)
  -F               Flip horizontally
  -f <rate>        Set frame rate (default: 10)
  -i <interval>    Set move interval in seconds (default: 0.2)
  -b <size>        Set border size (default: 2)
  -h               Show this help message

Design: snake
  -W <color>       Set worm color (R,G,B, default: 0,228,48)
  -l <length>      Set initial worm length (default: 5)
  -m <length>      Set maximum worm length (default: 100)

Design: random-pixels
  -I <squares>     Initial active squares (default: 10)
  -m <ticks>       Maximum random ticks (default: 100)

Design: text
  -t <text>        Set text (default: text)
  -f <font size>   Set font size (default: 14)
  -T <color>       Set text color (R,G,B default: 255,255,255)
  -d <direction>   Set initial direction (0: horizontal, 1: vertical default: 0)

not sure if all the options combination works, but this is a first step into making some order in all things

[fanfani]

some options are conflicting, for instance:

-f

general option:

-f <rate> Set frame rate (default: 10)

conflicts with text design option:

-f <font size> Set font size (default: 14)

-O

general option:

-O <color> Set border color (R,G,B, default: 0,0,0)

conflicts with cm5 design option:

-O <color> On color (R,G,B, default: 200,10,5)

-d

general option:

-d <design> Set design (default: snake)

conflicts with text, cm5, text-arcade options:

-d <direction> Set initial direction (0: horizontal, 1: vertical default: 0)

i would suggest using some convention for handling general and specific options. for instance, we could have uppercase options for general and lowercase for design-specific switches
