- Paint custom colors
- Use trig to position a shape
- Use variables to make shapes change properly when the window is resized.

END OF Hw2 and Quiz 2 MATERIAL
Style Counts!
Starting with hw3, and increasingly on each subsequent homework.
- Naming
Use well-named variables. Single-letter variable names are only acceptable in special situations, like "x" and "y" for coordinates. In general, variable names should be whole words (like "left") or even multiple words (like "rectangleLeft", which may hold the left side of a rectangle).
- Capitalization
Capitalize variables in lowerMixedCase and classes in UpperMixedCase, as shown.
- No "magic numbers"
Any number that is not -1, 0, 1, or 2 is a magic number and should be stored in a well-named variable for clarity and generality.
- Formatting
Indent and space your programs like the sample code provided (more on this later).
- Commenting
Provide clear and concise comments where needed to clarify your code. Never provide obvious comments (like "add one to x" on a line that reads "x++;"). Your comments should not say what the code does (your code says that!), but why it does it that way or some other clarifying text.
- UI
Provide a clear and concise user interface (UI), whether in a console or a GUI (graphical user interface). Unless otherwise directed, provide prompts for input, clear explanatory text for output, and meaningful error messages.
