Some pixel values in the numeral shader are not accurate.

I think there's no way to get 87 of 255 to print correctly, for example. The solution is probably to use integer textures like GL_RGB8UI and usampler2D

But integer formats don't work with mipmaps. GL_RGB32F works, but it increases latency. Let's leave the small errors for now. "Off by 1 at most".

Workarounds possible:

• Create a host side graphical annotation
• Put the true value in the status bar as you mouse around
