sw_engine: fix safety check
...
An incorrect check introduced in bf07eb11f2#1327 issue. As a consequence rotated images
were not drawn. Fixed.

common picture: support image mesh feature
...
Tvg Picture newly provides mesh() api to support texture mapping.
These apis allows to have a coarse triangle list which have polygon coordinates
and texture uvs those are used for traditional polygon texture mapping.
Note that these apis are beta version.
@API Additions:
Result mesh(const Polygon* triangles, const uint32_t triangleCount) noexcept
uint32_t mesh(const Polygon** triangles) const noexcept
@Examples:
//Mapping with two polygons
Polygon polygon[2];
//First polygon
polygon[0].vertex[0].pt = {0, 0};
polygon[0].vertex[1].pt = {100, 0};
polygon[0].vertex[2].pt = {0, 100};
polygon[0].vertex[0].uv = {0, 0};
polygon[0].vertex[1].uv = {1, 0};
polygon[0].vertex[2].uv = {0, 1};
//Second polygon
polygon[1].vertex[0].pt = {100, 0};
polygon[1].vertex[1].pt = {100, 100};
polygon[1].vertex[2].pt = {0, 100};
polygon[1].vertex[0].uv = {1, 0};
polygon[1].vertex[1].uv = {1, 1};
polygon[1].vertex[2].uv = {0, 1};
//Apply polygons to the picture
picture->mesh(polygon, 2);

sw_engine texmap: implemented fast span-edge anti-aliasing

sw_engine raster: improve the transformed rle image rasterizer.
...
replace the transformed rle rgba image with the texmap raster.
this patch removes the several scattered transformed image rasterizer,
reuse the unified one texmap method instead.
yay, it's much clean and optimal.

Unrolled the blending stages by applying macro magics.
I know this is a bit bad for code readibility
but good for the performance and the optimal LOC.

sw_engine texmap: introduced texture mapping polygon drawing.
...
Introduced the texture-mapping algorithm for the image-scaler.
With this approach, we can support any arbitrary forms of the transformed shapes
while appling the scale factors - x/y separately.
Also this is more efficient when the transformed image is far from the rectangular form
because our current normal image rasterizer based on the given drawing region whereas
our new approach is span-based.
Thus, we applied this mechanism only for the transformed images.
