invalid operands of types '__complex__ int' and 'int' to binary 'operator>='

I got this error in Arduino IDE 1.8.19 (Windows)

invalid operands of types '__complex__ int' and 'int' to binary 'operator>='

I stumbled across this issue a few minutes ago and decided to investigate the issue again. I found a slight syntax mistake on Lines 1227 and 1254.

Mistake:

for(int i = columns - 1i >= 12;i--) has to be for(int i = columns - 1; i >= 12;i--)

Explanation

A for loop consists of three parts, that are each separated by ; (Semicolon). You simply forgot some Semicolons.

• the first statement gets executed before the code block, it's mostly used for defining variables (e.g. i = 0)
• the second statement defines the execution condition. If this condition is false, the loop stops (e.g. i < number)
• the third statement gets executed (every time) after the code block has been executed. You can use it to increment a number (e.g. i++)
