fix warnings from previous commit

Batch struct initializer needed more {{braces}}

Gawain: multiple VertexBuffers per Batch

So we can store (for example) vertex positions in one buffer and normals + colors in another buffer. Not super exciting right now, but very useful once we start changing some attribute values.

Supports future work by Cl�ment et al. Only tested with one VBO per Batch since that's all our current code uses.

OpenGL: remove deprecated calls

glMaterial
glColorMaterial
glPixelTransfer

and glEnable/Disable for
GL_FOG, GL_LIGHTING, GL_COLOR_MATERIAL

All of these were just setting default values, so I don't expect any visible change.

Part of T49165 (general OpenGL upgrade)

Refactor: remove goal springs in favor of per vert computation

manual sanity clean up for preconditioner

necessary when changing grid size. internal grid has to be freed and reallocated to match new grid size

Store active screen-layout per window

Fix crashes on file read

Move window level workspace data into struct managed by workspace code

small fix for extrapolation function

distance argument was not int - was problematic with uneven divisions size

fix "Modern Viewport" regression

GPU_viewport_bind & unbind should be called as pairs. A recent commit -- 3b91989a093aef874b601efcffd247cf61e73bad -- called unbind only for some code paths, overflowing OpenGL's matrix & attrib stacks.

OpenGL: remove packed imm mode functions from Python API

These are from the ARB_vertex_type_2_10_10_10_rev extension that became part of OpenGL 3.3.

So they are new, but only exist for compatibility with immediate mode, which is old.
