Frozen app when switching branches and loading a font used while working with the other branch

[FlorinTulba]

Context: After working with any font family FF on the prototypesCUDA branch, when switching to branch _version2.0 and performing a test with the FF font, the application freezes.

Problem: Floating point precision is different between the 2 branches:

• prototypesCUDA uses single-precision
• all other versions use double-precision

Current Solution: Delete all previously generated files (which would get reused by the new branch) from:

• Pic2Sym/x64/DebugOrRelease/TinySymsDataSets
• Pic2Sym/x64/DebugOrRelease/ClusteredSets

When those files are not found, they get generated using the floating point precision specific to the current branch.

Possible Fixes:

• Either ensure that both branches can deal with any type of floating point precision
• Or force double-precision floating point for data serialization on all branches

Fixed by this commit.

Chosen Solution: Forced prototypesCUDA branch to serialize tiny symbols data as double-precision values instead of single-precision.
