Abandon all hope. Make LLRender2D mostly static variables to reduce overhead caused by getInstance locking

Provide method of storing joint indices sep from weight data for faster runtime processing.

Rename llround(..) to ll_round(..) because of a collision with MS llround (long long round) in VS2013

re-introduced don's refactor of low-level openGL calls pulling out of llui
and putting them into llrender. Took the new code from their updated versions
from the CHUI merge, but put them in a place accessible to appearance utility.

Removed most llappearance -> llui dependencies (LLTrans remains).  Moved LLInventoryIcon::EIconName into LLInventoryType.  Moved LLInventoryIcon back to newview.  Moved LLUI gl_* functions into llrender.

fixed bad parameters in draw3d...name tags should display properly now

added draw3D to LLUIImage to encapsulate display of image in projective 3D space

all param values now support named values uniformly

fixed regression where profile window wasn't using requested size

EXP-648 FIX As a developer, I want to be able to specify param blocks that use Multiple<LLUIImage> for a sequence of images
Factored out param block data classes so that specialized param block types, such as LLUIImage, LLFontGL, LLRect, etc. can be stored in a Multiple<T> context
Converted loading_indicator to take image sequence from XUI
deprecated name-value pairs for LLUIColor values, and put them in colors.xml

Image "none" wasn't being properly converted to a NULL pointer,
so was drawing the default gray image.

Backed out changeset: cfa60aef8061, added setBlockFromValue so setting a LLRect param in code will set the individua

added setBlockFromValue so setting a LLRect param in code will set the individual left, right, top, bottom values, for example
don't call setupParams when creating widgets from code
moved Multiple param constraints into BaseBlock to remove extra scoping
