If reusing dynamic textures, do not reuse small data length textures that fall below current viewer discard level 2 thresholds.
Viewer LL 3.3.4 and before sometimes fail to properly redisplay dynamic textures that have a small data length compared to pixel size when pulled from cache. This appears to happen when the data length is smaller than the estimate discard level 2 size the viewer uses when making this GetTexture request. This commit works around this by always regenerating dynamic textures that fall below this threshold rather than reusing them if ReuseDynamicTextures = true This can be controlled by the [Textures] ReuseDynamicLowDataTextures config setting which defaults to false.
