- const uint32_t* Picture::data(uint32_t* w, uint32_t* h) const

Returning pixel data is not guaranteed as the picture may contain vector resources.
Remove it unless it's absolutely necessary.

74954db56d common paint: refine the bounds() api to return the values after applying transformation. 
Current paint::bounds() returns the coordinates under the raw status,
the values are not quite useful if the paint object has the transformed children.

Thus, we extends the feature and give an additional parameter "transformed"
to return the coordinates values after transformation by user demands.

This is also necessary for tvg format, since we need the exact view size of the scene information.

The previous api is deprecated and we introduce a new api to replace it.

@APIs:
+ Result Paint::bounds(float* x, float* y, float* w, float* h, bool transformed) const noexcept;
- Result Paint::bounds(float* x, float* y, float* w, float* h) const noexcept;

f1d9f691cc tvg_saver: fix the incorrect stroke transformation 
Saver tries to pre-transfom to skip the matrix data,
but it missed the case - transformed stroking,

we skip it also only when xy scaling factors are same excluding the dash properties,
because scaled of the stroking is depent on the engines,
we have no idea of the proper input data in advance.
