Default mosaic tile size for higher res texture maps

[Hypnotron]

The default tile size for mosaic texture map exports auto adjust so that the width x height of the mosaic matches that of the heightfield.

In other words, if you have 1024x1024 heightfield with 256x256 pixel tile size resulting in 4x4 mosaic and then you generate a texturemap that is 8196x8196 (4x the resolution of the heightfield) then when you go to export the texturemap, the tile size starts off as 256x256 resulting in a 32x32 mosaic. Instead, the tile size for the texture map should default to 2048x2048 which would result in a 4x4 mosaic.

Hi Mike,

I can see why you'd want this. Rather than hard-coding this as the new default, I'll put a flag in the local preferences that sets the texture wizard default to either this behaviour (constant number of tiles), or the 'old way’ (constant tile size). This is on the to-do list for beta3.

Cheers,
Aaron.
