Simplify the handling of free texture indices by using `-1` only for indices which are currently in use, whereas the size of the vector is now used to indicate the last free index. Otherwise the assertions incorrectly detect the last texture index always being in use because `-1` was used for both states.
Use `enum EImageFormat` type for image format literals and variables.
Add `PixelSize` function to get the number of bytes/color channels per pixel for a specified image format.
Remove unused store format argument of texture loading functions. All textures are automatically being stored as RGBA, so the argument was unused. Also remove the therefore unused `FORMAT_AUTO`.
Rename variables consistently to `PixelSize` and use `size_t`, instead of mixing different names like `BPP` and `ColorChannelCount`.
Validate image format loaded from maps using `CImageInfo::ImageFormatFromInt`. Add `FORMAT_ERROR` to represent invalid formats.
Remove redundant `PixelSize` parameter from graphics backends and commands, which can be derived from the texture format.
Fix memory leak when RGB image data is being converted to RGBA format when saving map in editor.
When memory for a command or data in the command buffer cannot be allocated in `CGraphics_Threaded::AddCmd` and `CGraphics_Threaded::AllocCommandBufferData` the command buffer is cleared so it should always be possible to allocated memory successfully on the second try. Therefore assertions are added and the return values and inconsistent checks of the functions are removed.
The usage of `AddCmd` is simplified by automatically deriving an error message based on the type of the template parameter.
Encoding the image as PNG and saving it to a file comprises the majority of the time when taking a screenshot.
To avoid the client freezing while a screenshot is being saved, this task is moved to a separate background thread.
Replacing the C standard headers with the C++ standard headers causes various `error: call to 'floor' promotes float to double [performance-type-promotion-in-math-fn,-warnings-as-errors]`, which are fixed by using the C++ std math functions or our own math functions instead of the C math functions.
- Use `absolute` instead of `abs` and `fabs`.
- Use `std::floor` instead of `floor` and `floorf`.
- Use `std::ceil` instead of `ceil`, `ceilf` and `round_ceil`.
- Use `std::round` instead of `round` and `roundf`.
- Use `std::sin` instead of `sin` and `sinf`.
- Use `std::asin` instead of `asin` and `asinf`.
- Use `std::cos` instead of `cos` and `cosf`.
- Use `std::acos` instead of `acos` and `acosf`.
- Use `std::tan` instead of `tan` and `tanf`.
- Use `std::atan` instead of `atan` and `atanf`.
- Use `std::pow` instead of `pow` and `powf`.
- Use `std::log` instead of `log` and `logf`.
- Use `std::log2` instead of `log2` and `log2f`.
- Use `std::log10` instead of `log10` and `log10f`.
- Use `std::pow` instead of `pow` and `powf`.
- Use `std::sqrt` instead of `sqrt` and `sqrtf`.
- Use `std::fmod` instead of `fmod` and `fmodf`.
- Use `direction(Angle)` instead of `vec2(std::cos(Angle), std::sin(Angle))`.
- Use `length(vec2(x, y))` instead of `std::sqrt(x * x + y * y)`.
- Remove unused `NormalizeAngular` and `AngularDistance` functions.
Reduce duplicate code and improve correctness by passing indices of quad, buffer and text containers by reference and always setting them to `-1` after they are deleted.
Also check if index is `-1` before trying to delete it to reduce duplicate code when calling the methods.
- use `CORNER_*` constants and add missing constants
- fix array variable names
- use `size_t`
- extract duplicate computation into constant
- use `ColorRGBA` instead of `vec4`
This allows a larger range of PNGs to be loaded while still maintaining
backward compatibility with older clients by annoying the user.
This warning can be enabled by the `warn-pnglite-incompatible-images`
key in the https://info2.ddnet.tw/info JSON, if the key is not there or
the JSON hasn't been obtained yet, the warning is disabled. Since the
JSON is cached across restarts, it'll be effective for initially loaded
images from the second start.
Fix pointer and pointer array variable naming
Huge renaming to match our rules
Used regex: (?!(return|delete)\b)\b\w+ (m_|ms_|g_|gs_|s_)[^a]\w+\[
(?!(return|delete)\b)\b\w+ (?!(m_|ms_|g_|gs_|s_))[^a]\w+\[
Further format static variables
Format almost all pointer names accordingly
Used regex: (?!(return)\b)\b\w+
\*(?!(m_p|p|s_p|m_ap|s_ap|g_p|g_ap|ap|gs_ap|ms_ap|gs_p|ms_p))\w+\b[^:\(p]

Fix CI fail
Fix misnamed non pointer as pointer and non array as array
Used regex: (?!(return|delete)\b)\b\w+ (m_|ms_|g_|gs_|s_)p\w+\b
(?!return\b)\b\w+ (ms_|m_|g_|gs_|s_)a\w+\b[^\[]
