apply fast track to fast up the image rasterization.
only shifted image doesn't need to have the matrix-transform computation,
we can avoid it by just shifting offset xy by simple caculating.

revert d520da2db8
After considered the scneario seriously,
this doesn't helpful for the performance at all...
just increased code complexity. earlier bad decision... revert it.
current image interpolation method is a bit awkward,
because xy scale different scale factor is not allowed.
we must improve the algorithm,
but now considering floating point precision,
we allow the interpolation by less ratio floating fraction.
Tasks can be disposed while the renderer referencing it.
Now, we can delete the tasks with lazy approach by introducing some tags.

To preserve the naming convention function '_rasterTranslucentImageRle'
is reanmed to '_translucentImageRle'. The '_rasterTranslucentImageRle'
function is though created - it checks the composition method and calls
the corresponding function. Missing functions are marked, but not implemented
(separate commit).
After 362d2df the fastTrack cases were applied even for shapes with clips.
These changes fixed this - the check whether a shape is a rect should be done
only if it has no clips.
This reverts commit cd5116b053.
Ah this breaks the Stress example due to Picture::duplicate() is not available...
Need to consider and come back again.
* common: added colorSpace() function
This patch introduces colorSpace() function for SW and GL engine.
* infra: change LoadModule:read() into LoadModule:read(uint32_t colorspace)
This patch changes LoadModule:read() into LoadModule:read(uint32_t colorspace)
* picture: implement passing colorspace into loader
This patch implements passing colorspace into loaders.
Loader->read is now called on the first update.
* external_jpg_loader: support colorspaces
* external_png_loader: support colorspaces
This patch introduces _STRAIGHT colorspaces (ABGR8888_STRAIGHT and
ARGB8888_STRAIGHT) whose colors are un-alpha-premultiplied. Unmultiplicated
colors are especially needed for wasm thorvg loader and svg2png / tvg2png.
Only C version now.
@issue: #791
removed invalid nullptr checks.
New allocation doesn't gurantee that returns nullptr when it's failed.
It's useless on the modern compliers and our policy respects it.
Since no antialiasing is applied for the fastTracking cases,
the shape's rasterization region needs to be edited. To establish
the rastered bbox, the rounding is performed before the bbox corners
are casted to the SwCoords.
