ECS with sparse array notes (EnTT style)

Intro

The below is a breakdown / bird's eye view of how a sparse-array backed ECS like EnTT or Shipyard works.

Please see the thanks and references at the bottom - without their help I would not have been able to share this breakdown with you... everything here is really just notes and rephrasing of what they've written already :)

Also, these notes do not cover archetype systems (like unity) nor adaptations of archetypes (like in Flecs). Though there's a couple comparative footnotes at the end.

Here we go!

Quirks of C

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

1. Combined type and variable/field declaration, inside a struct scope [https://godbolt.org/g/Rh94Go]

struct foo {
   struct bar {
 int x;

Fix SVGs not scaling in IE9, IE10, and IE11

Fix SVG in <img> tags not scaling in IE9, IE10, IE11

IE9, IE10, and IE11 don't properly scale SVG files added with img tags when viewBox, width and height attributes are specified. View this codepen on the different browsers.

Image heights will not scale when the images are inside containers narrower than image widths. This can be resolved in 2 ways.

Use sed in bash to remove width and height attributes in SVG files

As per this answer on Stackoverflow, the issue can be resolved by removing just the width and height attributes.
