Encoding panel clarifications

The encoding panel mentions "None" in a few places, which is confusing.
- "Codec: None" now reads "No Video"
- "Audio Codec: None" now reads "No Audio"
- "Output Quality: None; ..." now reads "Constant Bitrate"

When selecting "No Video" the remaining video encoding options are
hidden, making it even more explicit that there will not be video in the
output file.

The label "Codec" now reads "Video Codec" for symmetry with "Audio
Codec".

BLF: Fix problem with bound texture.

Previous code was assuming that the glyph texture would remain bound to
GL_TEXTURE0 until the cache would be drawn. This is not always the case,
so better save the texture and rebind it before drawing.

BLF: Opti: More clever sampling for blured glyphs.

Reduce the number of sampled required for blurring by using filtered
texture samples.

This changes the result a bit but it is not noticable.

BLF: Opti: Draw only one quad per shadow/blurred glyph.

This port the Blurring of blf fonts to the final drawing shader.

We add a bit of extra padding to each glyph so that jittering the texture
coord does not sample the neighbor glyphs.

Fix edit-mesh select next

Last change introduced error, return would stop looking over candidates.

D3137 by @nBurn

Bullet: Fix velocity calculation of new spring constraint

This is a backport of bullet commit: 86ca7dc

UI: Fix waveform widget text drawing.

Flush the text cache so that we have proper scissor test and ordering.

UI: Perf: Port color widgets to batch.

This is more for completeness than perf.

Shader is tiny bit more complex but we get less overdraw and drawcalls.

Fix object mode workspace check

Minor change to last commit

Delete object crashed (missing NULL check)

Error in recent removal of workspace.object_mode

UI: Perf: Optimize F-curve handles drawing.

50% less time in my test when all handles are selected.

UI: Perf: Use widget base batching

Overall 10% more performance on general UI drawing time.

This commit can introduce ordering problem on some elements.
In this case you need to flush the widget cache to ensure the element that
is going to be drawn is drawn on top of any widget base.

To flush the cache use UI_widgetbase_draw_cache_flush.

This is already done for BLF and Icons.

Style: Remove duplicated struct declaration.

UI: Perf: Add batching capability to widgets.

Similiar to how we batch Icons together. This is not enabled in this
commit.

GPUShader: Add GPU_SHADER_2D_WIDGET_BASE_INST shader.

This will let us draw multiple widget base at once.

Fix Collada: nullptr is a c++11 keyword. Changed to NULL

Fix Collada: Import of animations for objects with multiple materials

When importing multiple materials for one object,
the imported material animation curves have all been
assigned to the first material in the object.

This fix also improves the console logging whenever the importer
finds a consistency problem with the imported animation data.

Cleanup: style, doxy headers

UI: Perf: Improve ui_draw_dropshadow.

Replace the 12 iterations of UI_draw_roundbox_4fv with only one batch.

This mean less overdraw and less drawcalls.

I had to hack the opacity falloff curve manually to get approximatly the
same result as previous technique. I'm sure with a bit more brain power
somebody could find the perfect function.
