* Set project name. Also fixed a bug
Added ability to set project name also fixed a bug that "if the aspect ratio button is pressed and a template of different width and height were selected, then the button also applied on them e.g a template of (but it shouldn't)"
Example: write 1 in width, 2 in height, enable aspect ratio, and then try to change template... a template of 256x240 will give 120x240

Not sure if that single if statement counts as branching code, but it's generally a good idea to avoid if statements in shader code, so I used step instead.
Cursor icon is temporary. It works by clicking multiple times on the places you want to create edges, and to complete the polygon you either have to click at the first edge (if you hover the mouse, a circle appears in that position), or you can auto-fill by double clicking.
Basically, when the background color of the screen at certain points is dark, the preview at that spot is white, and when it is bright, the preview is white at that spot. This helps to keep the previews always distinguishable, regardless of the background color.
Icons most likely temporary. A bit problematic when the selection is in negative coords and the preview does not work well with mirroring and mirror view. Same is true for the shape tools.
Related to the PoolVectorArray locking issue (#331). This still doesn't fix the issue itself, but at least Pixelorama does not crash anymore. It is still possible, though, to fail to load a guide when opening a project. Opening it again may solve the issue.
* a minor visibility change.
made the nodes that were not needed in wide-screen "Invicible"
the visibility will now be controlled procedurally
* Added some lines of code in "change_ui_layout()"
The added lines will control node visibility changes to adjust to current screen mode
* added a line to fix tall-screen "zen-mode"
Moves selection with contents by default.
Control + arrow keys = Moves & snaps selection to grid.
Alt + arrow keys = Moves the selection itself without the contents.
