* Draft implementation for SWS scale
* Update go.mod
* Revert "Update go.mod"
This reverts commit 760fb8c427.
* Renaming to AllocSwsContext and remove ChangeResolution this should handled by users
* update example to use new name and remove ChangeResolution
* Follow scaling example from libav, update readme, improve sws
Change scaling example to an similar libav example
Update readme
Add func to UpdateScalingParameters
Rename AllocSwsContext to SwsGetContext
Using a type for scaling algos/flags
* Fix Errors in scale example
* Review Changes
Now using sws context flags
Restructer sws context and adding ned simpler methods to update the ctx
Update the example
Update the test
* Correctly handle error for buffer alloc in PrepareDestinationFrameForScaling
* Add more getter and setter for sws
Get/Set source w,h,pixfmt
Get/Set dst w,h,pixfmt
Get/Set sws flags
* Adding resolution get/set
* Use CachedContext when updating sws ctx
* Review changes
Reorder flags, and update them
# Update Example
Use renaming function to create sws context
Clean up
Use new framdata image funcs
# Sws scale context
New way to update the context
Use sws_scale_frame instead of sws_scale
Reordering funcs for get and set
# Sws sclate context flag
Add "Flag" for algo name
# Update sws test
* fix fmt error args bug
* Review Changes
Simpfy sws update
Use c.int for sws flags
