eefcb62588 SDL_MUSTLOCK() returns true once a surface has the RLE flag set 
This more closely matches the mental model of people using SDL, and locking a surface that isn't RLE encoded doesn't cause any issues.

de6595bda6 SDL_MUSTLOCK() should return true if the surface needs locking even if it's currently locked. 
There's a bunch of code that assumes this in SDL, and presumably in applications as well.

334962b056 Enhancements for SDL_PremultiplyAlpha() 
The function can now convert between pixels of different formats, and takes a parameter to control whether the premultiplication is done in sRGB or linear space.

Also added SDL_PremultiplySurfaceAlpha(), which can premultiply the pixels of a surface in-place.

5db08b86ca Fix warning for Android NDK compiler: "function declaration without a prototype is deprecated in all versions of C [-Wstrict-prototypes]" 
https://stackoverflow.com/questions/42125/warning-error-function-declaration-isnt-a-prototype
In C int foo() and int foo(void) are different functions. int foo() accepts an arbitrary number of arguments, while int foo(void) accepts 0 arguments. In C++ they mean the same thing.

5f5e91eab6 Reverted 3d2e5a0b66eca4ade34f2a4fa81c8f4d8d33dac3 
Applying these changes to external code doesn't actually improve anything, and within the context of the other Get* functions for renderers and surfaces, these stand out as outliers, so I'm going to back this change out.

9ca1792848 Renamed driverdata to internal 
This was done to SDL_DisplayMode for consistency with SDL_Surface and gives it a type so we don't have to do casts in SDL code.

I considered switching to an ID and hashing the driver data, etc. but all of that involved a lot of internal code churn and this solution gives us flexibility in how we handle this in the future.

After consideration, I made this renaming global across the project, for consistency.

this.
