* Don't try to use labels in unsupervised losses
I hope that is the right way of fixing this...
* fix it by duplicating most code in send_job (works on my machine)
I will probably need to find a way to reuse the code
* try to fix it reusing the code... not sure though
* Revert "try to fix it reusing the code... not sure though"
This reverts commit f308cac6df.
* check the type of the training label to fix the issue instead
* Missing include for `dlib::loss_multiclass_log_per_pixel_::label_to_ignore`
I was trying to compile the examples and encountered this issue after moving `rgb_label_image_to_index_label_image` to cpp file. Headers should include all symbols they mention.
* Update pascal_voc_2012.h
Should use the official entrypoint for including dnn stuff.

* add progress information (current/total and percent)
* print a new line instead of overwritting with spaces
* check if target_val is an integer with std::trunc
* add function to compute string dimensions in pixels
* use custom struct as a return value, remove first and last params
* Update dlib/image_transforms/draw_abstract.h

* added support for std::optional if using C++
* oops, bug fix + check if item already holds a type
* oops, another bug fix
* remove warnings about unused parameters

Also fix this error from cmake 3.5.1:
```
CMake Error at CMakeLists.txt:62 (if):

"CMAKE_COMPILER_IS_GNUCXX" "AND" "CMAKE_CXX_COMPILER_VERSION" "VERSION_LESS_EQUAL" "4.8.5"

* [TYPE_SAFE_UNION] use std::aligned_union instead of stack_based_memory_block. std::aligned_union was specifically designed to do this kind of stuff and we are better off trusting the standard library deciding what the correct storage type should be and what the appropriate alignment should be
* [TYPE_SAFE_UNION] as per Davis' suggestion, std::aligned_union can take Len parameter 0. Also, the content's of validate_type() has been bugging me for ages, so i created is_any which is based on std::is_same. I've also replaced is_same_type with std::is_same
