Disable RenderUseAdvancedAtmospherics in feature table to prevent Ultra from turning it on before its time.

The 'all' section must be set to the value for high end machines as the minimum of high-end and recommended setting will be applied

Make more settings between mac and windows the same
Remove solaris and xp featuretables, since we don't support them any more

Rename the settings that control them to be more descriptive
Remove the separate boolean setting (RenderUseImpostors) that governed both
Establish default values based on gpu class for impostors and visual muting

MAINT-2086 Separate GPU class from settings more completely to avoid GPU dependent behavior when manually adjusting detail slider.

MAINT-1491 Integration of statistically generated GPU table -- enable shadows by default where appropriate.

MAINT-793 Pop up notification when drivers are likely out of date.  Allow Lighting and Shadows on Intel when drivers are up to date.

MAINT-808 Disable indexed texture rendering and deferred rendering on Linux when OpenGL version is pre-3.0

MAINT-708 Add checkbox to hardware settings for controlling texture compression.  Default texture compression to on for cards with 512MB of VRAM or less, off otherwise.

SH-2276 Fix for TDR's on GTX 460 et al -- don't use texture units above 16 (workaround for prevalent driver bug)

storm-1581: modify feature table rules to increment version only when the intent is to reset all graphics preferences

SH-2031 Disable usage of glMapBuffer (again).  Despite using MapBufferRange, this is still a source of frame stalls.

Followup on mapbuffer work -- only use map buffer where map_buffer_range is available, and allow non-buffer-mapping implementation to take advantage of recorded mapped regions.

SH-1387 Class0 video cards default avatar physics to high

Added appropriate featuretable entries.

Added appropriate featuretable entries.

Eliminated more merge artifacts.

SH-971 Fix for local lights flag not getting set properly on xp and linux when adjusting graphics quality setting.

Revert to previous behavior.  Reflections stay at "minimal".

Added opaque water default settings to Linux featuretable.

VWR-21349 Don't enable FBO by default on mac or linux when using high/ultra graphics.  Cap samples in LLMultiSampleBuffer to 4 samples to avoid using tons of memory when RenderUseFBO is set to TRUE and RenderFSAASamples is > 4.  Don't allocate multisample buffers at all when RenderUseFBO is FALSE.

SH-287 FIXED Anti-aliasing setting does not take effect until relog

Added logic to control RenderUseFBO setting based on graphics quality.  RenderUseFBO controls whether anti-aliasing is enabled.

STORM-1126 WIP Windlight Estate Settings port from 1.23: first pass at merging in windlight estate settings to viewer-dev codebase.

not built, not tested. Probably needs a bunch of fixes to be able
to be integrated.
