48e7f4191f gsktexture: Allow attaching render data to textures
This allows renderers (or anyone really) to attach "render data" to
textures. Only the first render data sticks.

You can gsk_texture_set_render_data() with the key you will use to
look the data up again, and if no data has been set yet, yours will be
set.

You can retrieve this data via gsk_texture_get_render_data() later on.
If your data has been cleared, NULL will be returned.

When gsk_texture_clear_render_data() is called (which the texture will
call when it is finalized), your destory notify will be called and you
have to release your render data.

The GL driver uses this to attach texture ids to GskTextures.

e161f9eba3 gsk: Add check on GL_MAX_TEXTURE_SIZE
We should check (once) what's the maximum GL texture size and then use
that size to check when we create any GL texture, to avoid errors.

0812d691b3 gsk: Reuse VAOs with identical buffers
Just like we reuse texture ids with the same size we can, at the expense
of a little memory, reuse vertex buffers if they reference the same
attributes and contain the same data.

Each VAO is marked as free at the end of the frame, and if it's not
reused in the following frame, it gets dropped.

702befc697 gsk: Recycle textures across frames
We keep the textures used inside a frame around until the end of the
following frame; whenever we need a texture with the same size, and
it's not marked in use, then we just reuse the existing texture.

24a6f3c055 gsk: Move resource handling inside GskGLDriver
We want the GL driver to cache as many resources as possible, so we can
always ensure that we're in a consistent state, and we can handle state
transitions more appropriately.

b169ce374e gsk: Rework surface -> texture API
Drop the texture parameters handling from the texture creation, and
associate them with the contents upload. Also, rename the function to
something more in line with what it does.

e2a43a8701 gsk: Add GL driver API to create render targets
It's going to be used by the GL renderer to safely create and bind
FBOs when needed.

8807f23f76 gsk: Split surface upload from texture creation
We're going to need a method to create textures without a surface.

46bb14e173 gsk: Add GskGLDriver
We can move the caching and management of textures, VAOs, and state of
the GL machinery into a single object, GskGLDriver.
