Fix #34249: collapse edges crash blender with a specific mesh

OpenMP block was using shared variable, which for sure leads to
threading issues.

fix [#34295] Color picker brightness to infinity
simply clamp the color to the buttons softrange since color conversion can cause the value to scale outside the intended button limits.

Fixes for alpha mode do_versions code

Before this change only old flag "Premultiply" was used to
detect alpha mode, which is not enough actually.

Now the logic here is:

- If "Premultiply" was enabled it is likely float image with
straight alpha, which shall be premultiplied before usage.

In this case image/sequence Alpha Mode is set to Straight.

- Otherwise use default alpha mode for image format based on
an extension. This could fail in some cases like TIFF, but
this wasn't handled fully correct in older blender anyway.

Initial discovered issue was that EXR images saved in older
Blender versions were set to Straight alpha mode, which is
obviously a straight way to lots of headache.

fix for [#34283] wasn't working in my tests (attached to original report),
made bone roll get compatible angle values with the original roll.

Bugfix [#34283] armature bones losing their roll setting upon translation in
edit mode

My earlier fix for [#33974] (in r.54061) was causing some problems where
manually specified roll values on horizontal or angled bones were getting reset.
This could be nasty as you might not notice the changes for a while (especially
when using stick bones without axes displayed).

I've now put in place a hacky compromise solution which should catch both of
these situations nicely. For z-axis (i.e. vertical) movements, the r.54061 fix
is used, while for everything else (moving or just touch-n-go), the old setting
is used.

bpy.props.RemoveProperty() had incorrect docstring.

minor change to own recent commit with transform fcurve centers and some style edits and typo corrections.

Fix for [#34099] Particles leaking from moving meshes

This was caused by a floating point precision error. During collision detection, Newton-Raphson iteration is used to find the exact time of the collision. But when using subframes, the initial Newton step was too small. Now the initial step is given in absolute units. When subframes = 0, this should behave almost the same as before.

Thanks to Janne Karhu, Lukas Toenne and Ton Roosendaal for their help with this patch, and to AutoCRC for funding.

Fix for [#34308] only half width of material list row is used for material name.

* Issue was caused in r54393.

Themes: disabled items on menus were using a color mix of text and text_selected, this didn't work nice with dark themes and text shadows and overall didn't make much sense.
Now, disabled items use a mix of text and menu item background (inner) color. Same results, but allows dark themes with bright selected text to use shadows.

Force movie clips always use default alpha mode, before this straight
alpha was used for them which doesn't work for cleaned footage stored
in EXR file format.

Perhaps we need to support configurable alpha mode for clips, but
that's for later (maybe even after release),

Correction to own r44749 -- layers from view were always used,
shall use active layer now for real.

Fix wrong alpha channel for OpenGL render results with transparent textures or
materials, the typical glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); blend
function does not give correct destination alpha.

fix [#34303] Rotation fcurves don't work with transforming with individual centers

checking for V3D_LOCAL was duplicated in transform.c, and both checks not quite correct.
- When checking edimode, make sure its mesh editmode.
- Graph editor supports this option but wasn't being checked.

Bug fix #34292

CTRL + MMB zoom in 2d editors now depends on 'max zoom' level. This makes
zooms in UI (very limited) go smoother, but for fcurve or timeline it's same.

Fix some popups being too small on retina display, among them the new image dialog.

Fix #34290: backface culling option in 3d view was not interacting well with the
option in the material in texture draw mode, now it always overrides the material.

fix bpy_extras.mesh_utils.edge_face_count_dict() helper api function.
it was using tessfaces when theres no need to.

Fix #34276: OpenGL render not doing color space conversion to linear correctly
with transparency, would show as too dark colors on edges.

Found a strange issue here though, the alpha value in the OpenGL render result
is not the same as the one specified in the material. It's not clear to me why
this happens, color space conversions should not influence the alpha channel.
