impr: Don't force using discrete graphics card on macOS (#1341) <!-- Please provide as much information as possible about what your PR aims to do. PRs with no description will most likely be closed until more information is provided. If you're planing on changing fundamental behaviour or add big new features, please open a GitHub Issue first before starting to work on it. If it's not something big and you still want to contact us about it, feel free to do so ! --> ### Problem description <!-- Describe the bug that you fixed/feature request that you implemented, or link to an existing issue describing it --> When starting ImHex on a MacBook model with both integrated and discrete graphics, it will force the computer to use the discrete graphics card. This causes increased power usage, meaning the fans will spin up, the battery will drain faster, etc. This program is not very graphics intensive, so using the discrete graphics card shouldn't be needed. ### Implementation description <!-- Explain what you did to correct the problem --> I changed the [`GLFW_COCOA_GRAPHICS_SWITCHING`](https://www.glfw.org/docs/latest/window_guide.html#window_hints_osx) setting in GLFW to not enforce using the discrete graphics. ### Screenshots <!-- If your change is visual, take a screenshot showing it. Ideally, make before/after sceenshots --> ### Additional things <!-- Anything else you would like to say --> My editor is configured to automatically remove trailing whitespace, so I hope that those whitespace changes are ok

Proper DPI scaling and basic custom font (#85) * add glm to arch deps After running got `None of the required 'glm' found`. This fixes that * dist/fedora: Include file magic headers Due to differences in package names between Deb based systems, Arch Linux, and RPM based systems the package containing the development headers for file were missing from the Fedora dependencies script. This includes the package `file-devel`, which is the package which resolves the issue. In Fedora, one can identify the package providing a specific file using the verb "whatprovides" with the command dnf, e.g.: [~]$ dnf whatprovides /usr/include/magic.h Last metadata expiration check: 4 days, 0:23:05 ago on Fri 04 Dec 2020 09:06:53 AM PST. file-devel-5.39-3.fc33.i686 : Libraries and header files for file development Repo : fedora Matched from: Filename : /usr/include/magic.h file-devel-5.39-3.fc33.x86_64 : Libraries and header files for file development Repo : @System Matched from: Filename : /usr/include/magic.h file-devel-5.39-3.fc33.x86_64 : Libraries and header files for file development Repo : fedora Matched from: Filename : /usr/include/magic.h If one is unsure of the specific path, globbing may be used (but must be quoted): dnf whatprovides "*/magic.h" Resolves #48 * dist: Prevent already installed packages in ArchLinux and MSYS2. Use --needed option with pacman to prevent it. * Add script to install dependencies on Debian/Ubuntu. Tested with Xubuntu 20.04 and Debian testing (in today's Docker image bitnami/minideb). Update README.md. * ci: rework (#31) * Support non standard LLVM library names (#86) This fix openSUSE and Gentoo issue mentioned in https://github.com/WerWolv/ImHex/issues/37#issuecomment-739503138. (tested on openSUSE tumbleweed via Docker) I also took the liberty of renaming llvm_lib to llvm_demangle_lib to be more specific in the ``CMakeLists.txt``. * Implement proper DPI handling * Implement basic custom font support * Fix building on windows * Hopefully fix fonts on Windows * Fix several scaling issues * Replace font renderer with freetype * Updated CI and dependency scripts * Rebuild default font atlas * Correct platform detection macro for mingw * Fixed PKGBUILD Co-authored-by: brockelmore <31553173+brockelmore@users.noreply.github.com> Co-authored-by: Brian 'Redbeard' Harrington <redbeard@dead-city.org> Co-authored-by: Biswapriyo Nath <nathbappai@gmail.com> Co-authored-by: Stéphane Gourichon <stephane.gourichon@fidergo.fr> Co-authored-by: umarcor <38422348+umarcor@users.noreply.github.com> Co-authored-by: Mary <me@thog.eu> Co-authored-by: WerWolv <werwolv98@gmail.com>
