introduce texture loaders to make allocations lazy
This introduces the internal idea of texture loaders that track the
state for loading and allocating a texture. This defers a lot more work
until the texture is allocated.
There are several intentions to this change:
- provides a means for extending how textures are allocated without
requiring all the parameters to be supplied in a single _texture_new()
function call.
- allow us to remove the internal_format argument from all
_texture_new() apis since using CoglPixelFormat is bad way of
expressing the internal format constraints because it is too specific.
For now the internal_format arguments haven't actually been removed
but this patch does introduce replacement apis for controlling the
internal format:
cogl_texture_set_components() lets you specify what components your
texture needs when it is allocated.
cogl_texture_set_premultiplied() lets you specify whether a texture
data should be interpreted as premultiplied or not.
- Enable us to support asynchronous texture loading + allocation in the
future.
Of note, the _new_from_data() texture constructors all continue to
allocate textures immediately so that existing code doesn't need to be
adapted to manage the lifetime of the data being uploaded.
