+Farbdraw
+
+Takes the concept of interval.rs sound generation and moves it over to image generation. 
+
+Users can update certain variables that continue on when not called directly, they can also have math oriented udpates as well as loops
+
+Possibility of functions (circle, square, etc)
+
+rgba averaging on draw where there is a previous layer
+
+different point sizes and a concept of soft or hard (hard being constant a channel soft being diminishing over time)
+  Lines can be drawn from a start point at an angle with a color soft or hard with an amount of pressure (that equates loosely to distance)
+  Points can be done mostly the same way
+
+Everything writes to rgba farbfeld.
+
+Possibility of user writable filter modules that can be activated via "use _______;" to do an opperation on teh whole canvas.

+Things have shifted to maybe doing image mangling based on input file. To do so I could just use the standard go image library to deal with the images.

+Operators:
+# Operators get applied to numerical values and always lead the number
+# = is implicit when writing just an int, but can be optionally included for clarity

++, -, / (floors on decimal), *, %, =

+
+Variables:
+# The following global variables are available
+
+WID # The image width
+HIG # The image height
+REG # A register for saving numbers?
+

+
+Setting the current pixel:
+# Valuesthat over or underflow the image dimensions will be looped to aceptable locations
+
+LOC int:int
+LOC [op]int:int
+LOC int:[op]int
+LOC [op]int:[op]int

+
+Applying changes:
+# Just calling APY alone applies the filter to the current selected pixel
+# Calling with a ratio sets the width and height of a square in which to apply the filter
+
+APY 
+APY [op]int:[op]int
+
+. . .
+
+Colors get set either individually or as a group:
+# Using COL as opposed to the individuals requires that all four values are set
+# Passing an int with no op sets to that value
+# Values udner or overflowing will loop to acceptable values
+
+RED [op]int
+GRN [op]int
+BLU [op]int
+APH [op]int

+
+Set the apply mode:
+# Using an op with MOD will always loop through the modes as needed based on the operator
+#
+# Values:
+#  0 - Hard mode, replaces pixel contents with the color settings on apply
+#  1 - Average mode, averages the incoming channel with the existing channel
+#  2 - Loop mode, adds the values of the existing and incoming channels and loops around on overflow
+#  3 - Fade mode, works as average mode, but uses the fade timer to fade over the course of a number of pixel adjustments
