Description
Add a 'reset' to canvas font so that it removes the current 'cache' of characters and textures to keep VRAM usage low.
During a long session, there may be an accumulation of textures that could be cleared out.

Research direction
Start by locating the Canvas Font API and reading how its character and texture cache is created and retained. Define the reset behavior around clearing that cache, then verify that subsequent font use rebuilds what is needed and that the accumulated textures can be released to reduce VRAM usage.
