cleanup from recent commits

coding style, float literals

Converted some (expr / literal) to (expr * literal) where it does not impact readability.

Simplified a few function calls.

OpenGL immediate mode: clip_graph_draw.c

Part of T49043 and T49042

OpenGL immediate mode: gluSphere replacement

Updated interface_draw.c to use the new sphere batch.

OpenGL immediate mode: fix Waveform Font color

OpenGL immediate mode: interface_draw.c (cont)

ui_draw_but_COLORBAND
Introduced a new checker shader to be used mostly on transparent areas.

OpenGL immediate mode: interface_draw.c (cont)

ui_draw_but_UNITVEC
Introduced a new shader to be used for simple lighting.

OpenGL immediate mode: Convert leftover UI_ThemeColor calls

Some `UI_ThemeColor` calls were left in converted files, in some cases
because they were just overlooked, and in the case of text drawing,
because the new BLF color functions were not yet implemented at the
time of conversion.

Also converted one `drawcircball` call that was left in
transform_constraints.c

Part of T49043

fix clang warning

uninitialized variable (glGen functions set the value)

OpenGL immediate mode: uvedit_draw.c

Still has one `UI_ThemeColor` call, because drawing is happening in a DM
drawing callback which hasn't been converted yet.

Also has some old gl calls that are #ifdef'ed out.

This also changes active face drawing in UVs from stippled to a solid
color, which makes active faces much more visible, and also looks nicer.
The same should probably be done for active face drawing in the 3d view.
(has been discussed with merwin on IRC)

Part of T49043

Use dummy versionning numbers for missing libraries.

We now assert that we now file version of libraries (needed for
do_version after linking step), so for missing libraries, set dummy
numbers (using version of main .blend file actually).

Use OBACT_NEW to show the object edit mode

De-duplicate min/max calculation in F-Curve normalization

Complete immUniform functions to support 2float and 3float

CTests: Initial work to cover Cycles nodes with OpenGL tests

Works similar to regular Cycles tests, just does OpenGL render to
get output image.

Seems to work fine with the only funny effect: Blender window will
pop up for each of the tests. This is current limitation of our
OpenGL context. Might be changed in the future.

Cleanup: Trailing whitespace

Cycles: Cleanup, move EdgeMap to blender_util

it's better place for such an utility structure. Still not fully ideal tho.

Cycles: Make an utility class for edge map

Simplifies some logic.

Cycles: Fix pointiness attribute giving wrong results with autosplit

Basically made the algorithm to handle vertices with the same coordinate
as a single vertex.

Cycles: Cleanup: Use less indentation by inverting condition

Cycles: Calculate all vertex attribute after faces generation

This way the calculation is not spread over multiple places.

Cycles: Cleanup: use vector instead of bare malloc

This way memory is more "manageable" and easier to follow.
