Niklas Haas	2d077f9acd	swscale/internal: group user-facing options together This is a preliminary step to separating these into a new struct.

Ramiro Polla	7728b3357d	swscale/range_convert: call arch-specific init functions from main init function This commit also fixes the issue that the call to ff_sws_init_range_convert() from sws_init_swscale() was not setting up the arch-specific optimizations.	3 months ago
Niklas Haas	67adb30322	swscale: rename SwsContext to SwsInternal And preserve the public SwsContext as separate name. The motivation here is that I want to turn SwsContext into a public struct, while keeping the internal implementation hidden. Additionally, I also want to be able to use multiple internal implementations, e.g. for GPU devices. This commit does not include any functional changes. For the most part, it is a simple rename. The only complications arise from the public facing API functions, which preserve their current type (and hence require an additional unwrapping step internally), and the checkasm test framework, which directly accesses SwsInternal. For consistency, the affected functions that need to maintain a distionction have generally been changed to refer to the SwsContext as sws, and the SwsInternal as c. In an upcoming commit, I will provide a backing definition for the public SwsContext, and update `sws_internal()` to dereference the internal struct instead of merely casting it.

Niklas Haas	c1a0e65763	swscale/internal: constify SwsFunc I want to move away from having random leaf processing functions mutate plane pointers, and while we're at it, we might as well make the strides and tables const as well.
