Functions
Clear screen (black).
Fill matrix with given color.
Return size of canvas.
Set pixel at (x, y) with color (r,g,b).

The way to completely initialize your matrix without using command line flags to initialize some things.
Create a new canvas to be used with led_matrix_swap_on_vsync() Ownership of returned pointer stays with the matrix, don’t free().
Stop matrix and free memory. Always call before the end of the program to properly reset the hardware
Get active canvas from LED matrix for you to draw on. Ownership of returned pointer stays with the matrix, don’t free().
Print available LED matrix options.
