Make columns resizable

[SanderMertens]

Issue
Currently the explorer layout is not resizable in the way that the v3 explorer was.

Solution
Make columns resizable for the following pages:

• Entities (tree icon)
• Queries (search icon)

@ryanhcode are you still working on this?

[ryanhcode]

@maxomatic458 yes! I've posted about it in the flecs discord. Will likely finish up the PR in the next day or two.

Is this still not done? Like is it still open?

@zelosleone didn’t solve it for you? @SanderMertens ?

I just closed the PR. It had a number of unresolved issues that prevented it from getting merged.

Can you specify what was missing.

The last commit's problem was mentioned in discord; I solved the most with last commit but let me show you with a video:

Ignore my edgy weeb music but using column icon at the right side when canvas is resized, it will give a flashbang like effect, resulting in in a "slow" motion. I think canvas is especially hard to sync here, but you can work from my pr if you wish to do so. Other than that, good luck.

@SanderMertens Would like to solve this for you but what was the error that came up with @zelosleone PR? We can talk about it more on discord or something so I am able to get at the root of what was unresolvable in the previous solutions. Because I don’t want to get started on something that will end up being the same issues that others have sent in PRs for and didn’t meet the requirements.

In summary this change should

• not change the layout of the explorer (the explorer should look pixel for pixel the same before resizing columns)
• not break window resizing
• not break the 3D canvas, canvas resizing or canvas aspect ratio
• not break the button that hides the left column
• work on chrome, brave, safari, edge (firefox is nice to have)
• work for both wasm mode (with 3D canvas embedded) and remote mode (connected to flecs app)
• have no bugs in the resizing logic:
  • when hovering the resize handle should light up
  • when dragging the mouse should always be above the resize handle
  • the column sizes should not "pop" while resizing the window or columns
  • the spacing between columns should not change

TL;DR it shouldn't break any existing functionality and shouldn't have any bugs in the resize logic.
