direct dropshadow image to ensure correct rendering.

for multiple image asset references.

Updated the data of active images in the pooler
within the override() function to resolve the issue.

8b37ec5d9c gl_engine: seperate the index buffer from vertex buffer 
WebGL has a strict rule that does not allow the same GLBuffer
to be bound to both ARRAY_BUFFER and ELEMENT_ARRAY_BUFFER at the same time.
(https://registry.khronos.org/webgl/specs/latest/1.0/#5.14.5)

To support WebGL in the future, a separate GLBuffer is used to store index data.

ed90581a1f sw_engine: fix render fill region 
Shape's bbox represents only fill's render region.
Render region of fill and stroke is stored in SwTask.
This was visible while rendering shapes with a stroke -
fill was to big.

a851d1706e lottie: fix transformations in text range selector 
Since the translate API was used while text updating,
the subsequent range selector transformations gets overwritten
when updating the shape (scale and rotate, adding another
translation will persist). This caused unexpected results.
Fixed by using the transform API when additional transformations
are needed - also fixes applying more than one range selector.

not depend on the direction of the shape. A positive
offset value expands the shape, while a negative value
contracts it. Fixed.
