Now, stabilizing is pretty enough.
Remove assert code so that we never abort process in any cases.
This also reduce the binary size.

We can use RGBA colorspace rather ARGB for pixel data.
This would be better for many rendering system,
since it's more widely preferred than ARGB including opengl.

replace dynamic_cast to static_cast,
This can be a controversial choice between optmization and clean code.
Obviously we know the converting types,
try avoiding a bit heavier casting some cases.

We prefer to build up a tiny compact engine at memory rather than compatibility,
this engine is not considerd for end-users but designed for middle-level framework
and some low-level users.
Thus, we won't consider 64bits data size,
use explicit 32 bits data until coming next upgrade...

Introduce Result type for notifying caller more detailed info.
We should implement the result values for each apis, with practical values.
