Write data only if needed

[aleve99]

Sometimes it is useful to write a series of draws in the framebuffer and then write all of them in the st7789 in one shot. I'm not an expert but I think it can be also more efficient.
The idea could be to pass show: bool = True in the function calls. And expose then an ST7789 method show() that would write the framebuffer to the st7789.
I would like to implement it myself but I've looked at the c code and I'm no so expert in c unfortunately.
Any chances to see this implemented?
