Rendering ofFbo to float textures with ES 2.0

ofTexture is setup so that it can take parameters to create a float texture targeting ES 2.0 like so:
void ofTexture::allocate(int w, int h, int glInternalFormat, int glFormat, int pixelType)
or in use:
tex.allocate(width, height, GL_RGBA, GL_HALF_FLOAT_OES, GL_RGBA);

I could be missing something, but from what I can tell if you want to have an ofFbo render into a float texture, currently you will have to modify the createAndAttachTexture() function inside ofFbo.

Right now it looks like this:

void ofFbo::createAndAttachTexture(GLenum internalFormat, GLenum attachmentPoint) {

    ofTextureData texData;

    texData.textureTarget = settings.textureTarget;
    texData.width = settings.width;
    texData.height = settings.height;
    texData.glInternalFormat = internalFormat;
    texData.bFlipTexture = false;
    texData.wrapModeHorizontal = settings.wrapModeHorizontal;
    texData.wrapModeVertical = settings.wrapModeVertical;
    texData.magFilter = settings.maxFilter;
    texData.minFilter = settings.minFilter;

    ofTexture tex;
    tex.allocate(texData);

    attachTexture(tex, internalFormat, attachmentPoint);
    dirty.push_back(true);
    activeDrawBuffers.push_back(GL_COLOR_ATTACHMENT0 + attachmentPoint);
}

But neither ofTextureData or ofFbo::Settings seem to have a glFormat attribute. So you could do something terrible like this and make all your fbo textures float textures :

void ofFbo::createAndAttachTexture(GLenum internalFormat, GLenum attachmentPoint) {

    ofTexture tex;
    tex.allocate(settings.width, settings.height,  GL_RGBA,  GL_RGBA, GL_HALF_FLOAT_OES);

    attachTexture(tex, internalFormat, attachmentPoint);
    dirty.push_back(true);
    activeDrawBuffers.push_back(GL_COLOR_ATTACHMENT0 + attachmentPoint);
}

Or perhaps a better way would just be to add the glFormat attribute to both ofTextureData and ofFbo::Settings. And then if there is a glFormat in ofTextureData it can just bubble down to fill in the glType.

This isn't an issue with GL ES > 2.0 since when you allocate a fbo you can give it the GL_RGBA32F, but since that doesn't exist in 2.0 we have this problem.

Is this just something that was overlooked? Am I overlooking the solution? Or just too niche of a scenario for anyone to have noticed until now?

Start by tracing ofFbo::createAndAttachTexture and compare its ofTextureData setup with the ofTexture::allocate signature and ES 2.0 usage shown in the issue. Inspect ofTextureData and ofFbo::Settings for how texture format and type are represented. Done means an ofFbo can render to a float texture under ES 2.0 without modifying the function with hardcoded allocation parameters.
