Bug Report: Text Renderer does not support removing /re-adding strings

[harrand]

Describe the bug The free list of string handles does not work. The vertex shader currently works by checking all strings in-order. This means having strings that are not in order of offsets is wrong and breaks horribly.

Reproduction

• Repros On: [tz_text_rendering_demo] (with local modifications to remove/add new strings over time)
• Repro Type: unexpected behaviour
• Repro Rate: every time
• Repro Severity (how badly does it affect your bottom line): high Repro Steps cba.

Expected behavior Users of text_renderer should be able to remove and then add new text without dodgy behaviour. They shouldn't need to worry about the internal sorting of strings having to be correct.

Screenshots N/A

Conditions (please complete the following information):

• OS: windows
• Render API: vulkan
• Build Config: debug
• Version: master
• Compiler: clang
