0007415: Var region can not load .raw (LLRAW) terrains bigger than 256x256
If trying to load a 768x768 .raw (LLRAW) terrain file into a 768x768 var region, it fails with the error message:

2015-01-15 15:38:24,779 ERROR - OpenSim.Region.Framework.Scenes.EventManager [EVENT MANAGER]: Delegate for TriggerOnPluginConsole failed - continuing. Unable to load heightmap: wrong size, use a file with size 768 x 768 at OpenSim.Region.CoreModules.World.Terrain.Ter

The same terrain loads fine as a .png or .r32/.f32 file, saves apparently fine as a new .raw (LLRAW) file, but can't be reloaded as a .raw, while it reloads fine if saved as a new .png or .r32/.f32 file. The length and structure of both original and freshly saved .raw file appears correct with a size of 7667712 (768x768x13) bytes and similar 13 byte repeat sequences.

My guess is the LLRAW loader either calculates the dimensions wrong or uses hard-coded 256x256 dimensions still for .raw files.
Create a 768x768 var region. Try loading a 768x768 .raw (LLRAW) file. See error in console and log.

Added patch calculating the terrain size for LLRAW the same way as for RAW32 instead of assuming default 256x256.

Committed as git master fad4d4d.

In this case, I had to add the missing "using OpenSim.Framework" statement to get it to compile.
