 DebugShowUploadCost Make LOD generation on model preview less finnicky.
 Remove error level based LOD generation. Better framing of model before
 upload. Better error handling for model uploader. Remove [COST] argument from
 model upload menu item. Remove L$ check from model upload menu item being
 enabled.

Subject: SH-373 Update glext.h, disable anti-aliasing on ATI when rendering
 deferred.  Get rid of RenderUseFBO debug setting (only use FBO when rendering
 deferred).  Use GL_ARB_framebuffer_objects instead of GL_EXT_...

Subject: SH-655 - Project mesh viewer crashes on exit. A copy constructor was
 implemented which did a memcpy, which included the vtable pointer which was
 to another object of another class (same child though).  This resulted in the

 purposes.

The solution was to move to LLVector4a, which is intrinsicly aligned.

Also, did some performance optimizations based on the LLVector4a optimizations.


The solution was to re-implement the

Subject: Cleanup of headless client (was: DisableRendering mode) * Now called
 'HeadlessClient' instead of 'DisableRendering' * Removed most cases where we
 skipped certain behaviors in the client when in this mode.  This gets us
 closer to a 'true' client, for testing purposes.

Subject: SH-1521 FIX -- Lighting and Shadows grayed out on mac

* Modified mac feature table to bring it up to date with latest renderer features including deferred rendering
* Changed mac AGL pixel format to no longer allow it to revert to software rendering when shader compilation errors occur.
* Fixed up various GLSL shader compilation warnings and errors that came up as a result of the above changes.
* Changed initial conditions for the "hardware skinning" checkbox on the preferences floater so it can be modified before login on machines that support avatar vertex programs.
* Removed unused avatarAlphaF.glsl files

Subject: SH-1618 FIX -- Lighting and shadows crash ATI macs

* Fixed ATI mac "lighting and shadows" related crash
* Fixed up numerous GL errors on macs related to multiple color formats,
  the use of glEnable/glDisable on textures above the texture unit count
  and old ATI-specific code that was not appropriate for Mac.
* Disabled SSAO for ATI macs due to it not working with shadows
* Ongoing work to properly get shadows and SSAO functioning on ATI macs is required.
