06461bba73 render: Move non-batching flushes to different place.
This lets us batch up a few commands that are all related to the same API
call.

2241b33f55 render: Update Metal and GL backends to use new high-level features, etc.
Now nothing is uploaded as dynamic data with Metal's setVertexBytes, etc; it's
all in the one big vertex buffer, now.

cc56de44a4 render: A bunch of high-level improvements.
- high-level filters out duplicate render commands from the queue so
  backends don't have to.
- Setting draw color is now a render command, so backends can put color
  information into the vertex buffer to upload with everything else instead
  of setting it with slower dynamic data later.
- backends can request that they always batch, even for legacy programs,
  since the lowlevel API can deal with it (Metal, and eventually Vulkan
  and such...)
- high-level makes sure the queue has at least one setdrawcolor and
  setviewport command before any draw calls, so the backends don't ever have
  to manage cases where this hasn't been explicitly set yet.
- backends allocating vertex buffer space can specify alignment, and the
  high-level will keep track of gaps in the buffer between the last used
  positions and the aligned data that can be used for later allocations
  (Metal and such need to specify some constant data on 256 byte boundaries,
  but we don't want to waste all that space we had to skip to meet alignment
  requirements).

a2f7af9a47 gles2: Make render command queue dynamic.
It now uses a growable linked list that keeps a pool of allocated items for
reuse, and reallocs the vertex array as necessary. Testsprite2 can scale to
20,000 (or more!) draws now without drama.

0d3275297d gles2: Major renderer optimization. Work in progress!
This moves all the rendering to a command list that is flushed to the GL as
necessary, making most common activities upload a single vertex buffer per
frame and dramatically reducing state changes. In pathological cases,
like Emscripten running on iOS's Safari, performance can go from a dozen
draw calls killing your performance to 1000 draw calls running smoothly.

This is work in progress, and not ready to ship. Among other things, it has
a hardcoded array that isn't checked for overflow. But the basic idea is
sound!

87bc1fb552 GLES2: Get sin/cos out of vertex shader
The only place angle is activated and causes effect is RenderCopyEx. All other
methods which use vertex shader, leave angle disabled and cause useless sin/cos
calculation in shader.

To get around shader's interface is changed to a vector that contains results
of sin and cos. To behave properly when disabled, cos value is set with offset
-1.0 making 0.0 default when deactivated.

As nice side effect it simplifies GLES2_UpdateVertexBuffer: All attributes are
vectors now.

Additional background:

* On RaspberryPi it gives a performace win for operations. Tested with
  [1] numbers go down for 5-10% (not easy to estimate due to huge variation).
* SDL_RenderCopyEx was tested with [2]
* It works around left rotated display caused by low accuracy sin implemetation
  in RaspberryPi/VC4 [3]

eb14b635cd Fixed bug 4134 - Render targets lose scale quality after minimizing a fullscreen window
Olli-Samuli Lehmus

If one creates a window with the SDL_WINDOW_FULLSCREEN_DESKTOP flag, and creates a render target with SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "linear"), and afterwards sets SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "nearest"), after minimizing the window, the scale quality hint is lost on the render target. Textures however do keep their interpolation modes.

888198ee31 metal: Misc. improvements.
- Use a single buffer for various non-changing constants accessed by the GPU, instead of multiple buffers.
- Do the half-pixel offset for points and lines using a transform matrix so we don't need a malloc when rendering.
- Don't add a half-pixel offset for other primitives and textures. This matches D3D and GL render behaviour.
- Remove the half-texel texture coordinate offset since it's not needed now that there's no more half-pixel position offset when rendering a texture.
- Don't try to set texture usage on iOS 8 since it doesn't exist there.
