style cleanup

Code cleanup: remove some remaining code from the old compositor.

Fix #33800: GLSL group nodes not using the external input value unless a node
was connected to the socket.

Fix #33875: minimize stretch UV tool incremented in steps of 0.2 instead of 0.1,
and now also shows the shortcut keys for setting the blend value.

Fix #33741,#33856: multi texture drawing problem with VBO's after a recent bugfix.

Render: set minimum render size to 1x1 instead of 2x2. As far as I can tell this
works ok, and it's useful for debugging.

Jpeg2000 should be saved with straight alpha

Follow general mathutils rules for naming straight<->premul functions

Minor UI message fix (from [#33101] Minor interface typo in User Preferences > Themes > Add Preset, patch by gdh, on IRC).

fix [#33781] Confusing units in displacement modifier parameters

16bit PNG images were not doing any conversions when saving linear float buffers, but would always load them as SRGB.
apply the same method used for 16bit images from floats as used in jpeg2000.

Spelling corrections

Two threading issues:

- Drawing masks in image editor requires LOCK_DRAW_IMAGE around
ED_space_image_get* functions since they'll acquire image buffer.

Lock is needed because viewers will be modified directly in
compositor (see commend in draw_image_main)

- Seems that was wrong order of invalidating render result and
viewer image invalidation happened in Composite node, which
could easily lead to thread lock.

write 16 bit PNG files even when there is no float buffer,
the existence of a float buffer can depend on the image being used in the compositor for example, so better give the user what they expect - 16bit png if its selected from the UI.

fix issue reported in '[#33876] bpy.path.ensure_ext adds extension twice / extra period if filename empty, just a period or equal to extension'

For python operators that used the ExportHelper mix-in class, an empty file field would become '.ext', entering and existing the text field would become '.ext.ext',
Now only add an extension if the filename part of the path is set, so '.ext' will still become '.ext.ext' but having only the extension isn't so likely to happen in the first place now.

This is a different fix then the changes suggested in the report but I'd prefer to keep path functions stupid+predictable.

replace vertex slide with the transform operator. (MESH_OT_vert_slide -> TRANSFORM_OT_vert_slide)

vertex slide was using flipped value, wasnt so noticable unless you types in a value.

Some fixes:
* handle nicely multiple empty lines in po files (still have to figure out why po writer sometime output two lines instead of one!)
* fix rtl processing!

displace modifier incorrectly had mid-level set as a 'distance' subtyped property.
also change the minimum texture contrast to 0.0 (was 0.01).

fix [#33831] "Alt" key is "Alt Window Deactivated"
Patch from Patrick Zulke (pazul)

remove NULL checks for BM_iter_new() element iterators. replace checks with assert().
