This changes a bit the batches data structure. Instead of using one
vbo per material we use one for all material and use index buffers for
selecting the correct triangles.
This is less optimized than before but has potential to become more
optimized by merging the wireframe data vbo into the shading one.
Also the index buffers are not strictly necessary and could be just
ranges inside the buffer. But this needs more adding things inside
GPUIndexBuf.
Shaded triangles are not yet implemented (request from gpumaterials).
This also changes the mechanism to draw curve normals to make it not
dependant on normal size display. This way different viewport can
reuse the same batch.
The issue was caused by a special code in node tree freeing function
which will free extra fields in the case when tree is not in bmain.
This is how old code was dealing with "nested" trees, but is now
making behavior different from other datablocks. This is exactly
what was confusing copy-on-write logic.
Ideally, ntreeFreeTree() need to behave same as all other datablocks,
ad freeing of data of nested trees should be up to the owner of the
tree (this way it's all explicit and does not depend on check of
some special flag.
Prefer legacy OpenGL library, for the compatibility and portability
reasons.
Also use proper OpenGL libraries to be linked against, so we can
change preference to GLVND.
this can be different though (e.g. vertex parenting) and correct location
is already stored in ob->orig

This restores the object->data to a non-modifier evaluated state.
So this allow us to change evaluated object modifier stack directly and
get BKE_mesh_new_from_object() for the evalauted object.
By default the text button background color was a similar brightness
to the cursor, making it hard to see at times.
Button types number/slider/text background brightness when editing
varied quite a lot too.
- Change the background while editing to match the number button.
- Darken the selection for greater contrast.
