[W.I.P.] suppress warning about implicit type conversions

I try to supress warnings, but I can't decide what is correct way in many situations. I think, rest of warnings are from gaps between C++ types and OpenGL (or other third-party library) types.

Maybe, we have to do force cast, but is it fundamental solution...?

for example, ofTexture::allocate:

• many ofTexture::allocate methods delegating to other allocate method with size_t arguments like allocate(pix.getWidth(), pix.getHeight(), ...)
• but width and height arguments of ofTexture::allocate is typed as int
• and allocate method that is finally called, w and h will assinged to texData.width, texData.height are typed as float

I can't decide what is right type to allocate.

what do you think...?

I suppose texData is float for a reason, like the tex hack to remove artifacts, so maybe ofTexture allocate should use float parameters? What do you think @ofTheo ?

What is the problem with implicit conversion other than the annoying warnings?

[dimitre]

@roymacdonald I think the warnings are there so we can make decision about control of the types. This specific one already brings the question : should a texture be allocated with float? if yes should ofTexture receive float parameters too ?
