Text on models

[Luomu]

Need a way to mark special geometry in models, generate text there (ship labels mostly)

[Luomu]

Perhaps best done using a named geometry, position & orientation will be used, geometry size is ignored

Hacked something together using TextureFont as the texture & geometry creator. Challenges:

• Text is huge, since TF is tweaked for pixel sized rendering
• Text is flipped for the same reason. Positioning is generally hard.
• Can't enable filtering without hacks. Should be alpha tested too.
• Estimating sizes is difficult.

Could be better to pre-generate a distance field glyph texture with a fixed character set, monospaced font, then not use TF at all.

Did this. Looks very crisp! Still need to do:

• font x/yoffset adjustments, not respecting xadvance at all
• font colour is hardcoded. The material should be probably definable in .model.

I'm considering the current state usable, material still cannot be defined but that can come later.
