Happy new year to the wonderful Godot community!

2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.

We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)

Here's to a great year 2021 for all Godot users 🎆

1e99e893ef Batching - fix proxy textures (e.g. animated) especially ninepatch
Ninepatch code has a check to prevent use of zero sized textures. This didn't deal properly with animated textures, which use a proxy (link to another texture).

This PR uses a generalised method of getting textures, with built in support for proxy textures and protection against infinite loops.

15e57a0235 Remove buffer orphaning options project settings
These were only put in for the betas, in order to test hypotheses for stalling on Macs. It seems that most of the problems in the Mac editor have been solved by fixing the excessive redraw_requests.

As a result no one has reported any results from these options, but in future we will be able to refer users to try the beta versions, so there is no need to include them in the stable release. Indeed they are only likely to cause confusion.

2d6cb3e208 Batching - Protection against zero and small sized ninepatches
Although the minimum size of ninepatches is set to the sum of the margins in normal use (through gdscript etc) it turns out that it is possible to programmatically create ninepatches that are small than this minimum - in particular zero size is used in sliders to not draw items.

This PR deals with zero sized ninepatches by not drawing anything, and has some basic protection for ninepatches smaller than the margins. Whether these occur in the wild is not clear but is put in for completeness.

4c588c21e8 Fix ninepatch batch break logic.
I'd forgotten to add check for need for a new batch. Fixes visual anomalies, particularly tab container.

7c4cf1c043 Batching - BackBuffer copy fix
For fixing a previous issue state.canvas_texscreen_used was reset to false at the start of each render_joined_item. This was causing a later shader that used SCREEN_TEXTURE to force recapturing the back buffer immediately prior to use, which we don't want.

This PR preserves the state across joined items, and also prevents joining of items that copy the back buffer as this may be problematic.

It turns out that the original issue that needed the line is now fixed, and the later issue is also fixed by removing it.

3c69377f10 2d Legacy - close vulnerabilities and more debug checks
While adding more debug checks to legacy renderer, I closed 2 types of vulnerabilities:

* TYPE_PRIMITIVE would previously read from uninitialized data if only specifying a single color
* Other legacy draw operations would fail in debug AFTER accessing out of bounds memory rather than before

Many calls to glBufferSubData are wrapped in a safe version which checks for out of bounds and exits the draw function if this is detected.

4ae797b802 Batching - more error checking options
This adds some more error checking options for development, and simplifies the control flow checks which now become debug asserts.

1394df3188 Prevent item joining with custom shaders using selected BUILTINs
Large FVF allows batching of many custom shaders, but should not join items which have shaders that utilize BUILTINs which would change for each item, because these will not be sent individually, and all joined items would wrongly use the values from the first joined item.

f84f1e8b81 Prevent poly color path when translating batches than are non-poly
A previous fix for poly colors had caused a regression in the rect behaviour, this PR re-enables proper translation of rect batches.

4cadae5713 Batching - blank UVs in polys that contain no UVs
Polys that have no texture assigned contain no UVs in the poly command. These were previously not blanked, leading to random values if read from a custom shader.

This PR just blanks them.

7183e3ce43 Fix 2d software skinning with scaled polys
In some situations where polygons were scaled, existing software skinning was producing incorrect results.

The transform inverse needed to use an affine inverse rather than a cheaper inverse to account for this scaling.

e88b4f330e Poly colors fixes
This adds support for custom shaders for polys, and properly handles modulate in the case of large FVF and modulate FVF.

It also fixes poly vertex colors not being sent to OpenGL.

df4ef8dfac Batching - use legacy path for antialiased polys.
Antialiased polys work by drawing a smoothed line around the poly after the main drawing. Batching draws polys as a series of triangles with no concept of 'edge', and when 2 polys are joined it becomes impractical to back calculate the edges from the triangles.

For this reason batching is disabled for antialiased polys in this PR.

5c8f497a24 Add project settings to manually specify API usage
As a result of the GLES specifications being vague about best practice for how buffers should be used dynamically, different GPUs / platforms appear to have different preferences.

Mac in particular seems to have a number of problems in this area, and none of the rendering team uses Macs. So far we have relied on guesswork to choose the best usage, but in an attempt to pin this down, this PR begins to introduce manual selection of options for users to test their configurations.

586285639a Fix lines used in item with custom shader
Lines are batched using the simplest fvf 'BatchVertex', however when used in an item with a custom shader material, it may attempt to translate to large_fvf without the required extra channels. To prevent this a special case in flushing is made to deal with lines.

f4cb88e232 Fix transforms in custom shaders using large FVF
In small batches using hardware transform, vertices would be drawn in incorrect positions due to the item transform being applied twice - once in the transform uniform, and once from the transform passed as a vertex attribute.

This PR alters the shader to ignore uniform transforms when using large FVF.

c2290dbedd Unified GLES2 / GLES3 Batching
Batching is mostly separated into a common template which can be used with multiple backends (GLES2 and GLES3 here). Only necessary specifics are in the backend files.

Batching is extended to cover more primitives.
