Fix right scrolling of an image bug!

[arduino12]

Hi,

I want to be able to scroll an image from left to right,
But apparently- it only works in the web simulator- see my demo of the bug here.

I found that the cause of this is here.

To my thinking - the quick-fix will be to rename image.shiftLeft(int16_t n) into image.shiftHorizontal(int offset) -
So it can accept a negative value and shift the image to the right as well.

But a better fix will be to rename it into shift(enum direction) or shift(int x_offset, int y_offset) -
So we can shift an image in all directions!

Thanks!

How about this? #427

Oh sorry I missed your PR @martinwork - it could solve my issue !

But sadly it seems that nobody here want's to merge it after reading the issue #351 from 2018 :(

Shame that people had to re-implemet this in the higher layer like this.

My goal is to add Hebrew font for my students - I wanted to do it in this DAL lower layer -
But it looks like I better do it myself in the .ts files so I don't have to wait 1+ years for a PR approvers.
Anyway I will close this issue now and will write my scrolling code using the .ts files. :)
